I use 555 to make a infrared transmitter with 40kHz output signal and I use LM 567 to do the decode in the receiver side. I have follow the data sheets of these two ICs to build the circuits, but they didn't work!!! :cry:
please tell me how to set the frequency of the output signal and how to set the frequency of the decoder if I use 40KHz infrared signal to do the communication. what values of the resistors and the capacitors that I should use??? :shock:
PLEASE HELP ME........I GET NO TIME.......
