Hey forum,
Slight problem with this touch switch I built. Once triggered, the circuit description says that in order to reset, pin 4 needs a low logic level. The circuit works great, but once I touch the sensor plate (pin 2) it won't turn off unless I disconnect the battery, and even then when I reconnect it the LED comes back on without touch activation. If anyone could tell me how to reset this damn thing, it would be greatly appreciated.
Thanks much, G
