Time Delay Relay circuit using 555 timer IC | Off delay timer Switch | UTSOURCE

In this 555 timer project, I have shown how to make a time delay relay circuit using 555 timer IC to automatically turn Off the switch after a predefined delay. You can also adjust the off delay time up to 20 minutes.

Download the PCB Layout for this 555 timer delay circuit from the following article

Required Components for the 555 timer project
1) 555 Timer IC
2) BC547 Transistor
3) 1000uF 16V Capacitor
4) 1k 0.25watt Resistors - 2 no
5) 10k 0.25watt Resistor
6) 1M Trimmer
7) LED 5mm - 1no
8) 1N4007 Diode
9) 12V SPDT Relay
10) Pushbutton
11) Connectors & IC Base
12) Acrylic sheet

I have made the complete time delay switch circuit on a homemade PCB.

I have used the 12V DC adaptor to supply the circuit. Please take proper safety precautions while working on 110V or 220V AC.

You can also adjust the delay time of the light switch from the 10 mega-ohm trimmer or POT.

If you want to use a 5V DC supply, then just use a 5V relay instead of the 12V relay. No other changes are required.

After watching the video, you can easily design this Delay Timer switch circuit for your home.

If you face any issues please let me know in the comment section.
