#98718 - Modulate Responding to: ???'s previous message |
Dear, Stanley Lio.
I'd like to add my explanation, IR Transmitter burst is 38 kHz, at least 6 burst will output a low at the receiver. If the 38 kHz sent with 6 burst and stop for about 6 burst will output a 500 Hz of 0 and 1 at the receiver. (Mr Singh Suggestion). Therefore the LM567 can be used as a tone detector as Mr. Russell Bull solve the idea. Any way, Thank you for addition explanation. Kurnia Brahmana |
