battery to Arduino ground Write a for loop (i = 0-255) which increments by 1 every 100ms and do analogWrite(PWMOutputPin, i) I then take a multimeter to measure the voltage between ground and the emitter … leg and what I'm getting is values between 0-4.5 volts while the battery has about 7.68V in it by measuring it directly. I thought the purpose of the transistor is to send the full voltage between …
