Hi all. I am after some urgent help please as this is needed working by the weekend
All soldered together transmitter works fine (bright or light in camera)
The receiver however is constant alarming. All solder joints have been triple checked and resoldered. The alarm responds to a tv remote (flashes led and blips buzzer) also when the transmitter is turned on and off the receiver led flashes off then back on so it is seeing the signal ok
The track did come away in a couple of spots so these have been jumpered to the next contact point with wire. Any help regarding this would be greatly appreciated. All caps and diodes etc are in the correct place with correct polarity. Only thing I can think of that I haven’t tried is turning the sensor around as both legs were the same length. However surely it just wouldn’t work and wouldn’t sense the tv remote if it was incorrectly polarised.
I have added a switch to silence the buzzer but looking at the circuit diagram this shouldn’t affect anything.
Please help as we need this for this weekend to trap a dog that has been missing for over 8 months
