The purpose of this is project to adjust the timing of when a bulb or a buzzer should go off. This is a dual transistor timer with Darlington pair circuit. In the picture the SW1 (switch one) is the trigger. That switch is already in a state where the circuit is active, (that is what is shown in the picture). can someone explain to me how this circuit works. this is my first as electronics year in as level and i know not much of electronics. thankyou.
