What is RFID?

Maybe there are many people that not know yet about RFID now. RFID stand for Radio Frequency Identification. RFID is a technology that serves to detect and identify an object through the data transmitted via radio frequency. The system requires a minimum of a tag (which serves as a transponder), a reader (who serves as interrogator), and sebuan antenna (which serves as a coupling device).

One important element in RFID is a data transfer. Data transfer occurs when there is connection between the tag and reader, known as coupling through either an antenna mounted on the tag or reader as illustrated in the following figure 1 below:

Make Programmable Line Follower Robot Based Microcontroller Atmega8535

Let we make programmable line follower robot based microcontroller Atmega8535 now. In here you will get more information how to make programmable line follower robot based microcontroller Atmega8535 likes know proximity sensor circuit diagram, microcontroller Atmega8535 circuit diagram, and also driver DC motor circuit diagram. In here we also give you source code Atmega8535 program that made from CodeVision AVR.

Part 1

In the part 1, we will show you all of schematic diagram of programmable line follower robot based microcontroller Atmega8535.

• Proximity Sensor (Line Sensor)

Programmable line follower robot designed to follow black line on the floor, so we need sensor that can do it. In here we use proximity sensor or line sensor to do this work. Proximity sensor work to detect a black line with using LED and Photo-diodes component that will detect light or not light changing like in figure 1 below:

Figure 1. Work Principle of Proximity Sensor

We can make our self proximity sensor easily with follow proximity  sensor schematic diagram like in figure 2 below:

Figure 2. Proximity Sensor Schematic Diagram

• Data Processing Microcontroller Atmega8535

To process data from sensor and also give command to driver DC motor circuit, we use microcontroller Atmega8535 to do this work. To know the schematic diagram of microcontroller  Atmega8535 as base in line follower robot, please see figure 3 below:

Figure 3. Data Processing Atmega8535 Schematic Diagram

• Driver DC Motor using L298

To make line follower robot can rotate the dc motor, we need driver dc motor. In this design we use L298 as main component in driver dc motor. We not design driver motor dc using transistor component but using Integrated Circuit (IC) L298. Here is schematic diagram of driver DC motor using L298 like in figure 4 below:

Figure 4. Driver DC Motor using L298 Schematic Diagram

Part 2

In part 2, we will show you source code of programmable line follower robot based microcontroller Atmega8535. This is software part that you can make this program using CodeVision AVR software that you also can download freely from this blog. 

We must need source code program to make our line follower robot can "think" good to work follow the black line on the floor. Here is source code program for line follower robot that we are designed.

#include <mega8535.h> 

unsigned char sensor; 

void main(void) 

{ while (1) 

{ 

sensor=PINA; 

sensor&=0b00000011; 

switch(sensor)

Active Antenna AA-7 HF/VHF/UHF, 3 to 3000 MHz

Construction:
The AA-7, which can be built from scratch or purchased in kit form from the supplier listed in the Parts List, was assembled on a printed circuit board, measuring 4 by 4-11/16 inches. A template for the pcb board is shown in fig. 2. You can either etch your own board from that template, or purchase the circuit board or the complete kit of parts (which includes the pcb and all parts, but not the enclosure). The kit comes with a 16-page kit instruction manual that gives step-by-step assembly instructions and contains additional information not covered in this article. Kit assembly time, working slowly and carefully, should take less than an hour. Most of the parts specidied in the Parts list are standard components and can be procured through conventional hobby electronics suppliers. However, some parts--J1, J2, S1, S2, and R5-- have particular physical mounting dimensions; the Printed Circuit Board is designed to accept these particular parts. In addition, Q1 and Q2 can be hard to find; however, it is possible to make substitutions provided that you can find a supplier. Suitable replacements for Q1 and Q2  re given in the Parts List. The telescoping whip antenna screw-mounts to the board; the screw provides contact between the printed circuit board traces and the antenna. To save time and trouble locating and ordering hard-to-find parts, a Special Parts Kit is also offered by the supplier listed in the Parts List. A parts placement (layout) diagram for the AA-7's printed circuit board is shown in figure 3. When assembling the circuit, be especially careful that transistors Q1 and Q2, and the electrolytic capacitor C4, are oriented as shown.
Although not shown in the schematic (Fig. 1) or the layout (Fig. 3) diagrams, an optional led power indicator can be added to the circuit. Adding a power indicator to the circuit allows you to tell at a glance if the circuit is on; leaving the circuit on, even though the AA-7 draws only about 0.7 mA, will eventually discharge the battery. Of coutse, adding an led will increase the current drain to by about 7 mA, but the red glow makes it obvious when the unit is on. If you decide to include the indicator in your project, power for the indicator can be easily taken from the switched 9-volt DC terminal of S2 (center terminal, right side, looking at the top of S2). Simply connect the positive voltage to the anode (longer wire) of the led and connect her cathode lead through a current limiting resistor of about 1000 ohm to a ground point on the printed circuit board, or as the author did fromt the frame of R5. Mount the led at any convenient point near the switch. Although not supplied with the kit, a custom plastic enclosure (with front and back panels) or a regular 'hobby' case of some sorts, and knobs for the switches and gain control is offered in the Parts list. The enclosure comes pre-drilled and silk-screened with the appropriate legends for all the circuit controls and connecteors, but is not equipped with holes for the whip antenna or the led (if you include

Parts List and other components:

Semiconductors:

Q1 = MFE201, SK3991, or NTE454. N-Channel, dual-gate MOSFET (see text)

Q2 = 2SC2498, 2SC2570, 2N5179, SK9139, or NTE10. NPN VHF/UHF silicon transistor (see text)

Note: If you use the NTE107 as a replacement, make sure to insert it correctly

into the pcb. The orientation is different than as shown on the parts layout

diagram. (e-c-b seen frontview for NTE107). See this Data Sheet

Resistors:

All Resistors are 5%, 1/4-watt

R1 = 1 Mega Ohm

R2 = 220K

R3,R6 = 100K

R4 = 100 ohm

R5 = 10K potentiometer, (pc mount)

Capacitors:

C1,C2,C5,C6 = 0.01μF, ceramic disc

C3 = 100pF ceramic disc

C4 = 4.7 to 10μF, 16WVDC, radial lead electrolytic

Auto-Fan, for automatic temperature control

Th1, the 50K thermistor, is a standard type. Mine was a bar or rectangular looking thingy. Available from Tandy/Radio-Shack.  Almost any type will do. I experimented with different models from 22K to 100K and all worked fine after replacing the trimmer pot. The one used in the above circuit diagram was a 50K model made by Fenwal (#197-503LAG-A01). This 50K was measured at exactly 25 °C and with 10% tolerance. The resistance increases as the surrounding temperature decreases. Tolerance for my application (cooling a large powersupply coolrib) is 10%. Another name for this thing is 'NTC'. NTC stands for "Negative

Temperature Coefficient" which means when the surrounding temperature decreases the resistance of this thermistor will increase.  I replaced my thermistor for a 60K hermetically sealed glass type since the environment for my application may contain corrosive particles which may affect performance on a future date. P1 is a regular Bourns trimmer potentiometer and adjusts a wide range of temperatures for this circuit. I used the 10-turn type for a bit finer adjustment but the regular type may work for your application.

R1 is a 'security' resistor just in case the trimmer pot P1 is adjusted all the way to '0' ohms. At which time the thermistor would get the full 12 volt and it will get so hot that it puts blisters on your fingers... :-)

R3 feeds a bit of hysteresis back into the op-amp to eliminate relay 'chatter' when the temperature of the thermistor reaches its threshold point. Depending on your application and the type you use for Q1 and Re1, start with 330K or so and adjust its value downwards until your satisfied. The value of 150K shown in the diagram worked for me. Decreasing the value of R2 means more hysteresis, just don't use more then necessary. Or temporarily use a trimmer pot and read off the value. 120K worked for me. Transistor Q1 can be a 2N2222(A), 2N3904, NTE123A, ECG123A, etc. Not critical at all. It acts only as a switch for the relay so almost any type will work, as long as it can provide the current needed to activate the relay's coil. D1, the 1N4148, acts as a spark arrestor when the contacts of the relay open and eliminates false triggering. For my application the 1N4148 was good enough since the tiny relay I used was only 1 amp. However, you can use a large variety of diodes here, my next choice would be a regular purpose 1N4001 or something and should be used if your relay type can handle more then 1 amp

Make your own AM Radio

Although radios are common enough and cheap, why not make your own from a few readily available components? For example, the design shown in Fig is uncomplicated thanks to the two integrated circuits, IC1 and IC2, and it will receive radio stations transmitting amplitude modulated (AM) radio frequencies, delivering your selection to a small loudspeaker.
Circuit Details :
The central component for the first building block is integrated circuit IC1, a ‘radio on a chip’. Essentially, its purpose is to amplify the small volt- age generated across the tuned circuit comprising the LC combination; that is, variable tuning capacitor VC1 in parallel with inductor L1. When the radio is ‘tuned in’ to a station by adjusting VC1, a small alter- nating voltage is generated across the tuned circuit. This is processed by the rest of the circuit to extract the informa- tion carried by this carrier wave. IC1 requires a 1.5V supply voltage, which is provided by transistor TR1, resistor R1 and potentiometer VR1, used as a variable resistor. Adjust- ment of VR1 alters the supply voltage and determines the sensitivity of the circuit. Capacitor C2 couples the signal from the radio frequency amplifier and detector stage to the second building block, a low-power audio amplifier based on IC2, which powers a small loudspeaker, LS1. Potentiometer VR2 acts as a volume control.

Getting started with microcontrollers

What you will need to program microcontroller

In the late 1970s and early 1980s, the cost of equipment for developing microcontroller-based systems was beyond the reach of most small companies. Now, however, there are many high school students already developing exciting PIC projects.
To get started you will need the following equipment and documentation:
• One or more PIC16C84s or PIC16F84s (the ’83 devices will also suffice)
• A Personal Computer running Windows 3.1 or Windows ’95.
• A copy of the latest MPLAB software available free of charge from Microchip Technology Inc.
• PIC microcontroller data sheets and application notes available free of charge from Microchip Technology Inc.
• A PICStart-Plus programmer. Programmers available from third party manufacturerswhich support the PIC devices will also be suitable.
• A circuit breadboard or similar means of circuit construction.
• A 5V DC power supply.
• Some light emitting diodes (LEDs), resistors and some 32kHz crystals.
• Test equipment such as a digital multimeter and an oscilloscope (not essential).

What makes a microcontroller useful?

PIC microcontroller

A microcontroller (or microprocessor) can be viewed as a set of digital logic circuits integrated on a single silicon ‘chip’ whose connections and behaviour can be specified and later altered when required, by the program in its memory. The great advantage of this, is that in order to change the circuit’s structure and operation, all that is needed is a change in the program – very little, if any, circuit hardware modifications are necessary. An alternative view is that a microcontroller is a state machine whose logic states are defined by its program. A microprocessor is the Central Processing Unit (CPU) of a computer and a microcontroller can be regarded as a microprocessor designed specifically for use in applications where machines such as automobile engines or washing machines are to be controlled. Often the distinction between microprocessors and microcontrollers is quite blurred, as there is considerable overlap these days in the classification of different types of computing devices. A typical microprocessor is a device used in workstation computers, whereas a microcontroller is usually less powerful and has special features such as PWM (pulse width modulation) and timer devices integrated on the IC specifically for use in the applications mentioned above.

Simplified operation of a microcontroller

Humans perform arithmetic using a decimal or base ten numbering system. Computers use a base two system with the digits 0 and 1 and, because there are only two possibilities, they are termed binary digits or bits for short. There are many ways of representing a binary set of states,

for example
• a mechanical or electronic switch with two states — on or off
• opposite directions of current or fluid flow
• two different pressures
• a positive and a zero voltage.
 

In digital electronic circuits, the last choice is the most natural. Circuits implemented using TTL (Transistor-Transistor Logic) technology use 5V to represent the binary value 1 and a zero voltage to represent 0. The circuits discussed in this book, although not TTL circuits, will use the approximately the same representation. To provide some robustness to the representation, voltages above 3.5V will be taken to represent a logical 1 and those below 1.5V to represent a logical 0. Readers new to the subject of digital electronics are urged to consult one of the many excellent books available on the subject,
A simple microcontroller consists of the following modules:

• An Arithmetic Logic Unit (ALU)
• One or more working registers (called accumulators in the past) for temporary storage during computations. A register is a small block of memory, often the size of a byte, where data is stored.
• Program memory (ROM) and data memory (RAM).
• A program counter.
• An instruction register with instruction decoder.
• The control unit.
• A stack.
 

The ALU is responsible for performing all arithmetic operations such as addition, subtraction and Boolean logical operations, including exclusive-or and bit shifting. Multiplication and division is usually accomplished by repeated use of addition or subtraction, but some devices (such as the PIC17CXX series) have hardware multipliers. The working registers are used by the ALU as temporary ‘scratchpad’ memory, for example, for holding intermediate results of arithmetic operations. A program is a set of sequential operations on data. The program memory is an area of memory where the actual sequence of instructions which make up the program is stored. Data memory is an area of memory where data such as the value of constants are kept for use by the program during its execution. The program counter is a register used to store the address of the next instruction to be executed. Because the program consists of instructions stored sequentially in program memory, the address of the next instruction is obtained by simply incrementing the number (that is, the address), contained in the program counter.
 

The instruction register contains the actual binary instruction that needs to be executed. The instruction decoder takes the binary instruction and decodes it to determine what operation the instruction must perform and which data it must use. The control unit controls the timing and sequencing of all operations necessary to correctly schedule and execute instructions. While an instruction is executing, the next instruction is fetched from the program memory and placed in the instruction register with help from the program counter. The instruction decoder then decodes the instruction and it is executed when the next execute cycle occurs.
 

The stack is an area of memory used to keep track of the contents of the program counter when subroutines are called. When data is written to the stack, it is stored at the ‘top’ of the stack. This operation is referred to as pushing data onto the stack. When data is removed from the top of the stack, the stack is said to be popped. A subroutine is a block of program code that performs a calculation or operation that the main program needs to do a number of times. Instead of repeatedly inserting the block of code at each position in the main program where it is needed, the subroutine is called when required. When a subroutine is called, the return address (that is, the address of the next instruction that must be executed when the subroutine terminates), is pushed onto the top of the stack. In other words, the program counter is first incremented to specify the address of the next instruction to be executed after subroutine completion and then its contents are pushed onto the stack. The address of the beginning of the subroutine is then loaded into the program counter so that it can be executed. When subroutine execution is complete, the top of the stack is popped and the address of the next instruction is loaded into the program counter again, so that the program can continue where it left off before the subroutine was called.

Emergency Light circuit

The idea for this circuit came when I was repairing my aunt’s emergency light. Bulb based emergency lighting has a low efficiency and ultrabright l.e.d.s provide greater efficiency and more illumination, with a much extended battery life. It was therefore decided to change from a 12V light bulb to a pack of l.e.d.s. To get constant light, a constant voltage technique was adopted, using the circuit in Fig.2. For more power saving, step-down switching is used in preference to step-up. This function is provided by IC1 in conjunction with diode D3, inductor L1 and capacitors C3 and C4.

Emergency Light circuit

The resulting output is a stable 5V and powers the 12 ultrabright yellow l.e.d.s D4 to D15. The l.e.d.s are grouped in pairs, each pair buffered by a resistor, R4 to R9. Diode D3 is a high-efficiency type – do not change it to a 1N4000 series type as they are less efficient in this role.
The network consisting of R1 and D1 is a power-on indicator. The network around VR1, TR1, R2, R3 and D2 is a low-battery indicator. Preset VR1 should be adjusted until l.e.d. D2 turns on when the battery voltage is low. Inductor L1 should be a toroid type in order to reduce radiated r.f. interference caused by the switching regulator IC1. It should be glued to the circuit board to prevent it from vibrating. A small heatsink should be fitted to IC1. The circuit efficiency was found to be around 80%, i.e. about 10% better than with the step-up switching technique. The circuit operates for about four times longer than the bulb-based one in respect of battery life.

Solar Tracking System

Description:
Solar is a non conventional source of energy, considering this we have developed solar panels so that we can fulfill our electricity need. But due to revolution of the earth, solar source i.e sun does not face the panel continuously hence less electricity is produced. The energy panel should face the SUN till it is present in a day.

The problem above can be solved by our system by tracking the solar energy. The block diagram below shows system architecture it consist of a LDR sensor senses max solar power which is being given to the Microcontroller through the ADC which digitizes the LDR output. Controller then takes the decision according to then algorithm and tilts the panel towards the direction of the max energy given by LDR with the help of DC Motor . The Motor is used to rotate the LDR to sense the max solar power.

PC interfacing module is used to give the feedback to the system monitoring unit. 

  

Description in detail:
On the monitoring station which receives the data send by the system. This data is logged into the PC. The RS232 converter is used to connect the microcontroller to PC which convert PC"s CMOS level to Controller"s TTL level n vice versa.

Limit sensors or Touch sensors are provided to sense the starting and ending position of the solar panel.

Keypad is provided to adjust the starting position of the solar panel.
