How will you modify an electroplating circuit to clearly indicate that the electroplating process is over?

An LED can be added to the circuit in the same way it is connected in a tester. While electroplating is still taking place, electric current will flow and the LED will be lighted up. The moment electroplating stops, so does the flow of current and thus the LED will also turn off.
