Presenting two ways to make a Timer circuit that remains OFF when connection is given and turns ON automatically after few seconds, depending on the value of Capacitor used in the circuit.
Here, I will show you two different ways to make this circuit using :
1. 555 Timer IC
2. Transistor
Pushing the push button switch turns OFF the output (LED), which then turns ON automatically after few seconds, influenced by the capacitance used.
