Description in this system, we must have an input remote which is known as the IR transmitter remote which does have many keys and there is also a receiver that receives the data from the remote. remotely send the different data value on the different button and receiver receive that value. when we press any key the associated led will be glow. and the rest of the LED will not glow. and in the next process, we will add the relay and the ac load with the system so the Arduino ir remote can operate the AC load too. the different buttons will associate with the different sources so that we can operate many appliances. that is cool to operate the thing via remote. as you all sew the center lock car key. the car key uses radiofrequency but this system uses IR frequency. we need to make the remote front facing towards the receiver.
