Connect RGB LED and WS2812B Strip to Arduino

This project is about connecting RGB LED and RGB strip. However, it introduces PWM (pulse-width modulation) to simulate analog signal in a Arduino digital pin. When Arduino connects to a WS2812B RGB LED strip with digital pin, the line protocol is introduced. So RGB LED and LED strip are the parts in this project, PWM and Protocol are the main idea in this project.

The source code are from https://create.arduino.cc/projecthub . Just search "rgb led tutorial", and we enhanced some codes for our project.

https://www.aliexpress.com/item/33008860640.html - AleExpress Power supply. For WS2812B, select 5 volt. 5A is good for 256 LED, 10A is good for 512 LED. Sorry, never try 1024 LED.
