I want to create an obstacle avoider mobot and I'm using this infrared receiver module. This is my schematic for the emitter
**broken link removed**
I used 120 ohms for R2 and 10uF for C1
and this is my receiver schematic:
**broken link removed**
I didn't used C1 here since I'm just testing yet, I used also LM324 instead of 2n2222.
The problem is when I start to give 5v on my receiver, it receives a pulse even if the emitter is not yet powered (the visible LED lights at random sequence). Even by just moving the breadboard it makes the visible LED light.
Another problem is when I now give a power to the emitter part, even if there's no IR LED, the receiver module still recognizes the pulse lighting the visible LED.
Can you help me here? Is this one about the electrical noise?
