What is the best way to cancel a 1 shot monostable 555 timer circuit? I have a timer built that goes on for about 2 minutes when triggered, but needs to be cancelled by a voltage (Basically the same voltage as the positive rail).
I have never needed to do this before, so I just connected to the + on the timing capacitor, which worked for the most part, but altered the time of the 555 because the trigger source to cancel the timer was a source that turned on some lights, but the lights were manipulating the capacitor because of the resistance to ground when the bulbs weren't lit. Any ideas?
