Moderator note: this thread has been split from 5 sec delay ON timer.
Can anyone explain what the resistor and capacitor on the top schematic on the left side of the 555 are doing and what the resistors coming in and out of the transistors are for? I want to use this method to power on some light panels but I'm only using 6 volts. I was not sure what was necessary or not. I was assuming the resistor and capacitor were there to short out the trigger pin and start the timer but there isn't any values. Am I correct? Any information would be good.
