I wish to implement my own ammeter by using the ADC (successive approximation) that built in the microcontroller. Is it we should put a pull down resistor at the i/p and compute the current which in term of the measured voltage and that resistor value itself(Ohm's Law), or that ADC itself able to read the current, or any others circuit needed to be add in, i dun know? thanks so much for your kindly reply.
