Hello. I am newbie, i am trying to put a small dc motor working and regulate speed with PWM generated by arduino. The transistor i am using is a bc547c. The problem is that the motor make a strange noise but doesn t spin (no its not damaged). Connected an amp to see the colector current and it inc…
