koracing Posted November 1, 2023 Report Share Posted November 1, 2023 I'm not sure hardware savvy, but what you want is a signal inverter or NOT gate setup - what you show there looks close to what I'm finding on google. Scroll down on this page to the NOT gate example and diagram: https://electronicsclub.info/transistorcircuits.htm Inputing a ground will output a positive and vice versa.
