I am trying to make a battery disconnect when a time of inactivity is up. I was trying to find how I could have a 555 timer which has a default time of 3 minutes, but could be continually refreshed when a push button switch is pressed momentarily (taking trigger to low) and discharging timing capacitor back to start. I looked at a monostable circuit but could not find a way to refresh timing.
I could put the Picaxe to sleep, but prefer total switch off, as it's a a remote control. I do not have anything built yet or circuitry, just wanted the timer part solved. Thanks
