I'm trying to figure out how to make a charge/discharge redstone circuit. Specifically: *As long as the signal strength is above 2, the output is off *When the signal strength falls to 2, the output turns on and stays on *When the signal strength reaches maximum, the output turns off again and returns to the initial state. The idea is that I'm going to take a comparator output from a tank so that I can refill the tank when it gets low, but not be running the machines that fill it all the time. I'm pretty sure I need a T-flipflop, but that's as far as I've gotten; I'm kinda terrible with redstone. Only "advanced" redstone I have access to is the redstone connectors from Immersive Engineering. Can anyone help me figure this out?
