Hi, thanks for your replies. I have another query though. I have since scrapped using standard remote controls(cause the 'device' that i am planning to make might have TVs in the vicinity and the sent signal can also do operations on the TV). I have decided to make up a simple remote using a small PIC(12f629 preferably), i only need to send 5 codes. I intend to use the TSOP34838(only one available here locally) which only works at 38Khz, which ofcourse would need to be generated in software using a timer etc. What i wanted to ask was if any one has worked with it before, is it reliable to do this? Also, if not, than i can get a simple IR Receiver that way there would be no frequency dictation.
