Digital Ac Ammeter Circuit Diagram. The complete circuit diagram of this digital ammeter project is shown in the image below. Now the question is that why the shunt resistor is needed to measure current.
In this schematic 30 volt dc source is applied to 40ohm load. Current passing through this load is measured with the help of shunt resistor and pic16f877a microcontroller. Digital ammeter circuit diagram using microcontroller is given below.

In this circuit diagram 30 volt dc source is applied to 40ohm load. Current passing through this load is measured with the help of shunt resistor and pic16f877a microcontroller. The construction of ammeter can be done in two ways like series and shunt. Digital ammeter circuit diagram using pic micro controller schematic.
