Amazing Colorful RGB LED Clock

Hello friends, this is RGB LED clock. You will get the time in 12Hr format and changing color of number automatically. In this project we used WS2812B LED strip which is available in online market easily. Also you can change the time from key. Here you will get five no of key to set time and color pattern. If you want to make this then just follow all the step and make your own RGB LED clock.
