Hi, I used this guide to hook up this 1.5v DC motor . The only difference is that I use a 3.3v controller instead of a 5v. Everything works fine, but I am not sure I understand how to control the voltage with PWM. If I use 3.3/255 = 0.013, the 1.5 volts should be reached when I set the PWM pin to 1…
