| Apr 27, 2021 at 6:33 | comment | added | Seamus | More details on your setup might be useful: hardware components, schematics of your wiring, even a picture of your motorcycle with sensor wiring. I can't comment on your software, but a few thoughts on your hardware: GPIO are high input impedance, and wiring of even moderate length can cause issues (false signals). In general, solutions that filter transients are worth a try. For example, you might try a low-pass filter near the GPIO pin. Many tutorials available - for example | |
