Hello friends..!!

Hope all are good.

Festivals are approaching near.

Some celebrates Diwali.

Some celebrates Eid.

Some celebrates Christmas.

Everyone will put fairy lights in their houses. These fairy lights are simple.

So in this project I will convert these simple fairy lights into dancing fairy lights or running fairy lights.

I have used only 4 running lights because I have only 4 channel relay module. If you are having more than 4 channel relay you can connect more fairy lights into relay.

This project will be done with the help of an elder in your family.

So, make these simple boring fairy lights into dancing fairy lights.

This is such an amazing project I made.

Watch the whole video how you can make this project.

If you like this project respect it.

Give me suggestions so I can improve it or any feedback you want to give to my YouTube channel.

Also you can give me suggestions on "What I made next project.?"

In video description I have given 14 fairy lights code. If you are having a 16 channel relay module, you can connect 14 fairy lights.

Steps to make this project

1. Gather components like Arduino, relay module ( I use 4 channel ), jumper wires and Plyboard box.

2. Decorate your home with fairy lights.

3. Now the end wires of all fairy lights must be place at one place.

4. Now take plyboard box and place Arduino and Relay module in it.

5. Now connect jumper wires from relay to Arduino as from circuit diagram.

6. Upload the code.

7. Now connect all the COM pins of relays like K1 com to k2 com to k3 com to k4 com pins with small jumper wire.

8. Now take all 4 fairy lights one end wire and connect with one wire of plug.

9. Connect second end wire of plug to COM pin of any relay.

10. Now remaining one end wire of all 4 fairy lights must be connected to K1 relay NO pin, 2nd light to K2 relay NO pin, 3rd light to K3 relay NO pin and last 4th light to K4 relay NO pin.

11. Now give +5v power to Arduino and connect plug to 220v power supply.

Your dancing fairy lights are ready...!!!

EXPANDED TECHNICAL DETAILS

Universal Festival Lighting Suite

This project provides a versatile LED controller with custom-designed light shows for multiple cultural and religious celebrations.

• Multi-Pattern Sequencer: The Arduino manages long strings of LEDs using a high-current MOSFET matrix. Users can toggle between "Christmas Red/Green," "Diwali Golden Glow," and "Eid Emerald Shimmer" using a physical push-button.
• Running-light Animation Kernel: Features a high-speed "Chase" algorithm where the duty cycle of each LED group is phased by 120 degrees, creating a fluid, moving light effect that appears professional.

Design

• Battery-Optimized Pulse: To ensure the lights last through the night on a single charge, the Arduino uses high-speed 500Hz PWM to reduce power consumption while maintaining apparent brightness.
