Two Auto-OFF Timer Circuits || 555 IC or Transistor

Presenting two ways to make a Timer circuit that turns ON the load when connection is given and turns OFF 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 ON the output (LED), which then turns OFF automatically after few seconds, influenced by the capacitance used.
