Hello! I was wondering if I could get some help on building a schematic with the following constraints:
An input for the circuit needs to be a tact-button with a debounce capacitor going into a KPP OR GPIO pin assigned as an external interrupt port. The driving port should be out of GPIO connected to the circuit with photo-MOS.
I am doing some research into circuit design for my company. I am attempting to create a circuit that will discharge slowly over time. The pieces in the circuit would include a GPIO that uses a photo-MOS for signal pickup from an external computer system.
