Hi all,
I have some question regarding this project's schematic.
Basically the transmitter will emit a 38Khz signal and receive by the receiver.
The receiver will always in low stage when it received the 38khz signal from the transmitter. When there is a object obstructed the signal. The receiver will goes to high stage.
my question is what is the purpose of the 555timer at the receiver side?
thanks for the reply
