How to Make Timer Delay Circuit,ON and Off (ic 555)

 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-
