Hi guys, 1st of all thx for taking your time. I'm now doing a project on IR sensor, and i would like to combine two IR sensor together(including two sets of tramitter and receiver), i'm going to link the two receiver circuit together to work with XNOR gate and a buzzer.
In the sense of once there is only 1 receiver detect the signal from the sensor the buzzer will sound, in the other hand, if both detect, the buzzer will not sound. Current the circuit is not working, i'm wondering if i was using the wrong Logic gate. Does anyone know about IR schematic? Thanks again.

Well the first step would be to share your circuit and we can all check out what is going on.
