How to make LM317 variable DC Power Supply with circuit diagram

In this LM317 project, I have shown how to make LM317 variable DC Power Supply with the complete circuit diagram. I have made the LM 317 circuit on the zero PCB and also share the PCB layout so that you can easily design this adjustable power supply using the LM317 voltage regulator and Transformer.

Download and print the PCB layout on the A4 page from:
https://easyelectronicsproject.com/mi...

You can use this circuit as a lab power supply, motor speed controller, LED dimmer, etc

Required Components for adjustable power supply:
1. LM317 IC https://amzn.to/3hyP7Ba
2. 1000uF DC Capacitors (2no)
3. 10uF DC Capacitor (1no)
4. 100nF Ceramic Capacitors (2no)
5. 1N4007 Diodes (6no)
6. 5 mm LED (1.5V)
7. 220-ohm Resistor (1no)
8. 1k Resistor (1no)
9. 5k Potentiometer (1no)
10. DC voltmeter (optional) https://amzn.to/3kogZJX
11. Heatsink
12. Connectors
13. Zero PCB
14. Stepdown Transformer. (12V-40V) 1.5Amp https://amzn.to/2Rywtig

Current and Voltage Limit of this LM317 circuit: 0-40V and 0-1.5Amps.
For more details on LM317 please refer the following video:

During the LM317 tutorial video, I have shown all the steps for making this DIY simple variable dc power supply.
Always take proper safety precautions while connecting the circuit with the 220V AC supply.

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