How to Make Timer Delay Circuit,ON and Off (ic 555)
This Timer circuit remains OFF when connection is given and turns ON automatically after a 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 a few seconds, influenced by the capacitance used.
These are the Components Required for making the circuit:
1. Using 555 Timer IC
• 555 Timer IC
• Momentary Switch
• Resistors: 47 K Ω, 330 Ω
• Capacitor: 100 μF
• LED
2. Using Transistor
• Transistors: BC 547
• Momentary Switch
• Resistors: 1M, 330Ω
• Capacitor: 100 μF
• LED
Other Requirements:
• Battery: 9V and battery clip
• Breadboard
• Breadboard Connectors
These are the Circuit Diagrams for making the circuit using:

Simple ON/OFF Timer using IC 555 Timer
Automatic ON/OFF Delay Timer Circuit Using IC 555 by Manmohan Pal
This is a simple On/Off Timer circuit made with IC 555, the timing of the Delay can be adjusted by the Capacitor and Resister Values, higher the resister- more time delay, similarly higher the capacitor higher the time delay.
This simple Timer circuit can be used to make a On Timer as Well as Off timer, we can make a Mobile phone Charger Timer using this circuit which will Turnoff Charging after specific time, the timing can be adjusted by varying the values of R1 and C1 .
We can also Make A Water Pump Off timer using the same circuit-
