Hiiiii...    Now we are going build a arduino board..before knowing this WHAT IS ARDUINO..??? it a combination of some hardware (say microcontroller)along with compatible software(ARDUINO Ide) Above pic shows the basic ARDUINO board with atmega328p as its heart.so,now in this post I will tell u how to make your own board.for doing this you should require Atmega328p ic with base 16 MHZ crystal oscillator 22pf capacitors 7805 Male headers etc....  If you buy a atmega328p,initially it is not ARDUINO Ide compatible microcontroller. So to make it a ARDUINO compatible mc you must burnboot loader to that ic..it's very easy and simple procedure for that process is explained below  To burn bootloder u must have an ARDUINO board and breadboard with required components. ARDUINO to breadboard connections is shown in below pic Burning the Bootloader If you have a new  ATmega328  (or  ATmega168 ), you'll need to burn the bootloader onto it. ...

Hiiiii frnds ...today iam with new prototype . i.e remote controlling of home appliances..this can control almost all electrical appliances using some common wireless technologies like IR remote control DTMF based controlling.. Tools I used here for developing this project is arduino ide.. Components for this project are Atmega328p ic's( one for IR and other for DTMF) Tsop sensor DTMF decoder which I used in earlier post Relays (as many appliances) 16x2 lcd's (optional) Below is the code for both IR and DTMF //for DTMF #include <LiquidCrystal.h> // initialize the library with the numbers of the interface pins LiquidCrystal lcd(6, 7, 5, 4, 3, 2); void setup() { pinMode(9,INPUT); pinMode(10,INPUT); pinMode(11,INPUT); pinMode(12,INPUT); pinMode(A5,OUTPUT); pinMode(A4,OUTPUT); pinMode(A3,OUTPUT); pinMode(A2,OUTPUT); // set up the LCD's number of columns and rows: lcd.begin(16, 2); ...

line follower robots work on basic concept of reflection of light, we use light sensors usually available in the market as a pair of photo diode and an LED. The concept is the LED keeps emitting light and if any obstacle comes in its way , then the obstacle will reflect the light and that reflected light falls on the photodiode. Now as we all know the property of photo diode is that it conducts when light falls on it...now the photo diode is connected to a "D" pin , usually known as data pin/signal pin...so now according to process we get a HIGH or logic of 5V when obstacle is there and "0V" when nothing. Now in the above diagram we can see that 3 pins are popping out of the sensor, namely + -D ..the "+" pin needs to be connected to 5V of arduino or any microcontroller you will be using. Now connect the black color wire to GND pin of your arduino or known as ground...or simply one can declare a pin as LOW and connect the black wire to it a...

                        Address,data and control busses: Microprocessor Microprocessor is processing device of every computing device. It is like an artificial brain. It needs to communicate with outer world. for example, It needs to communicate with Input devices to get data,it needs to communicate with memory to process data according to instructions written in memory and finally it needs to communicate with output devices to display the output on O/P devices. To communicate with external world, Microprocessor make use of buses. There are different types of buses used in Microprocessor: Address Bus: It is a group of wires or lines that are used to transfer the addresses of Memory or I/O devices. It is unidirectional.In Intel 8085 microprocessor, Address bus was of 16 bits. This means that Microprocessor 8085 can transfer maximum 16 bit address which means it can address 65,536 different memory locations. This bus ...

Friday, 6 February 2015 hii guys today we are going to work with "DTMF BASED MOBILE OPERATED ROBOT" its easy diy OVERVIEW In this project " Cell Phone Operated Land Rover ", the   robot is controlled by a mobile phone   that makes a call to the   mobile phone attached to the robot . In the course of a call, if any button is pressed, a tone corresponding to the button pressed is heard at the other end of the call. This tone is called   DTMF   (dual-tone-multiple-frequency).The robot perceives this DTMF tone with the help of the phone stacked in the robot. The received tone is processed by the ( ATmega8 ) microcontroller with then help of DTMF decoderMT887o. The decoder decodes the DTMF tone into its equivalent binary digit and this binary number is sent to the microcontroller. The   microcontroller   is programmed to take a decision for any given input and outputs its decision to motor drive...
