| Jul 30, 2020 at 2:04 | comment | added | Delta_G | It's all about capacitance. The micro is putting a voltage on that cap sensor and measuring how long it takes to fall or rise. That gives a measure of capacitance. When you put your finger you change the capacitance. Perhaps you could put a second plate there and get the capacitance right to not trigger the button and then have a capacitor that you can switch in to make it higher and trigger it. Not entirely sure how you'd do that, but maybe it gives you a place to start. | |
