Help. Tried several NE555P circuits from online posts but can't get any to work, well except one that partly worked.
I basically need help understanding from a beginners point of view, the only issue I have seen consistently is all tutorials talk as if you have a grounding in electronics or building, I have neither.
What I want to do is build a circuit that is a variable timer in seconds
It has a start state with two LED's, A red one that is lit and green one that is unlit.
Press a button, the Red LED goes out
After the specified time, the Green LED lights up
IF at any point in the button press the button is released during the time to wait, the timer resets back to 0 and user has to press the button again and start the holding process again.
Once the timer has elapsed, the Green LED lights up and the button can be released, the timer then resets for next press.
Can someone point me in the right direction on how to do this? I have about 60 NE555P chips and want to make 20 of these timers for a game.
