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
