... or does your garage door open...put the batteries back in and press something metallic onto one of the 2 "squiggly" button contacts.. Then try the other.. Does the LED blink rate change or anything else..
Or you hear a boom followed by a large cloud of smoke..... or does your garage door open...
The interleaved fingers of conductive track either side of the LED are the switch contacts - they normally have silicon rubber button pads with conductive rubber blobs on the back that bridge those "fingers" when you press the button.I have no idea where any of the buttons (if there were buttons for this device) would have made contact. Could you please explain? I am a novice. Thanks a lot.
The suicide bomber training school should have at least one practical exam.Hopefully a suicide bomber lost his detonator!
It could be an IR transmitter - if the LED didn't produce visible light.So,.....could this be some sort of transmitter?
