555 Timer Circuit Diagram With Potentiometer. As discussed in the above section, the IC is in its standard monostable mode. One of the potentiometers is tune and the other is fine tune.
The output load is driven by the relay switch which is in turn controlled by the timer circuit.
This circuit achieves only a approximate value.
