hi!
i wanted to control my dc motor speed, so i made an astable multivibrator ( analog cuz i want to learn to do it manually)
this schematic works okey ( the dc motor speed increase and vice versa) and the transistor doesnt get hot so much ( when i prevent with my hand to run to motor forward)
but i have a doubt, is this really a PWM DC Motor Controller? or i just made something else?
