Vizier87 Active Member Jun 23, 2011 #4 allow me to offer an alternative: PT2262 and PT2272 receiver and transmitter ICs. You'll need IR transceivers or RF modules. Search the datasheet via Google. Cheers. Last edited: Jun 23, 2011

S Shyamal New Member Jun 23, 2011 #5 Thanks for your help. My circuit's problem is the photo-transistor. I don't know the model number of the photo-transistor. that is the main problem.
