WebMay 5, 2024 · I'm aware of the whole concept of dither which is necessary to avoid stiction in the solenoid valve. As most of you will be aware of, we cannot freely choose the pwm frequency in the arduino but are restricted to a few discrete frequency values of which only 30.5Hz (Pin 3,9,10,11), 61Hz (pin 5,6) and 122Hz (Pin 3,9,10,11) are below 200Hz.
