Arduino PWM As you may know, two PWM outputs of Arduino Uno are linked to the timers. For the “common” PWM, if we write a value from 0 to 255 on a PWM pin, the Arduino library will drive the assigned ...

It also makes life a lot simpler to have a 32-bit processor with lots of memory and a high clock speed. You might also argue that the Arduino has so many daughter boards (it pains me to say shields).

It could be that the workshop’s only crystal-backed generator that can run from 0% to 100% duty cycle is still broken, or it could be that it is simply an enjoyable bite-sized problem to ponder at ...
