need circuit
Universal remote control means a single remote can be used to operate your VCD,DVD, TV, Music system. and same equipments of others also.
I think this is quite complex
for standard remote control u need a encoder chip, keypad and ir led thats it. this will make a remote
and on reciever there is decoder.
and for universal u need lots of encoder chips in your remote.
