Introduction: Triac Control 220v Automatic Night Light Using Transformerless Power Supply

By www.diyproject.in
About: I like to make diy electronics,electrical and life hacks projects.

Hello everyone,

Today I will show you how you can make a Triac control 230v automatic night light.

In this project we will use triac instead of using relay. Also we will use transformerless power supply to reduce the total cost of this circuit.

In this project I wanna thank to " LCSC.COM " for providing me the necessary components..

They provide a lot of electronics components at very cheap rate.

Also they provide components datasheet.....

So let's do it .......

Step 1: Watch the Video

Step 2: Components Required

1. 224J Capacitor, 400v………………………….https://goo.gl/2yo5w1

2. 1 Megaohm resistor, 1/4 watt……………….https://goo.gl/1encPg

3. 1N4007 diode*4…………………………………https://goo.gl/vZM7uU

4. 100 ohms resistor, 1 watt or above……….https://goo.gl/Vc9q89

5. 470 uf capacitor, 35v or above……………..https://goo.gl/Dxy6BC

6. 5.1v zener diode, 1 watt……………………….https://goo.gl/Y1X7kD

7. 10k Resistor, 1/4 watt…………………………https://goo.gl/6dQY6o

8. LDR (Light Dependent Resistor)……………https://goo.gl/s9mMMT

9. Bc 547 Transistor or Any NPN Transistor……….https://goo.gl/nBCmo6

10. 220 ohms Resistor*4, 1/4 watt…………………https://goo.gl/DTuYXH

11. MOC3021 Optocoupler IC…………………https://goo.gl/eW8qgw

12. BT 136 Triac……………………………https://goo.gl/mAaGuD

13. Connector*2( optional )……………..https://goo.gl/jTxAmk

14. Universal Pcb………..https://goo.gl/XAWcez

15. 220V Power Supply Cable

16. Any 220V Load like Led Bulb

Step 3: Order the Components

As I told earlier..LCSC.COM one of the largest electronics components supplier in China...

  • They provide the components worldwide.....
  • Here are some best thing about LCSC.COM
  • A lot of components available
  • Price is very cheap
  • 4$ off at first order
  • Fast delivery, Very good packaging for every components with details
  • Also they provide components “Datasheet” , So you don’t need to find Datasheet at different website.

Step 4: Circuit Diagram

Step 5: Assemble the Circuit

Step 6: Caution

“Please Do not Touch any component while the circuit is plugged in.

This is not an Isolated circuit. This can give you badly shock. Do it as your own Risk. I/HowToBro will not be responsible for any unwanted situation.”

Step 7: Test the Circuit

Step 8: Done

Now you are done....

You can use it in your garage, garden also this can be use as street light.....

Step 9: Thank You

Thank you everyone ....
