RF REMOTE..

Want to make everything wireless..??? Huh.!! Then u r at right place. There are many wireless technologies like ir,DTMF,rf etc of these IR and DTMF are covered in earlier posts. So now its time for radio frequency communication.. Dont be get puzzled
In this post I will direct you how make simple RF remote..
So for making remote,components that you required are
*HT121D
*HT121E
*RX TX MODULES
*1.1M ohm resistor
*55k ohm resistor

 Now its time to know about encoders and decoders.encoders is a thing which creates some data at transmitter end. Decode is opposite for those encoders it simply decode the data which has been transmitted by encoders..so from this we conclude that encoders should always lies at transmitting section and decoders lie at receiver section

 MAKING A TRANSMITTER:



MAKING A RECEIVER:


This is how rf MODULES looks

ADC....¡¡

The Analog World Microcontrollers are capable of detecting binary signals: is the button pressed or not? These are digital signals. When a microcontroller is powered from five volts, it understands zero volts (0V) as a binary 0 and a five volts (5V) as a binary 1. The world however is not so simple and likes to use shades of gray. What if the signal is 2.72V? Is that a zero or a one? We often need to measure signals that vary; these are called analog signals. A 5V analog sensor may output 0.01V or 4.99V or anything inbetween. Luckily, nearly all microcontrollers have a device built into them that allows us to convert these voltages into values that we can use in a program to make a decision. What is the ADC? An Analog to Digital Converter (ADC) is a very useful feature that converts an analog voltage on a pin to a digital number. By converting from the analog world to the digital world, we can begin to use electronics to interface to the analog world around us. Not every p

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. You can do this using an A
