Story

About Project

This is very interesting and easy project as in this project you only need Arduino Uno or Arduino Nano, Leds of same colour or of different colours and some connecting wires.You can connect almost 10 to 12 leds with arduino so that you get more interesting results for yourhard work.

Demo video

Please watch the complete video to know how it works……

And like, share, comments on this video if you are new subscribe to our channel and follow on Arduino

In this I am providing 4 different source code for arduino upload all 4 codes one by one for better result.

I hope you enjoyed my project.

Thanks!
