From this experiment, you will learn how to use an RGB LED module which can be used as multiple LEDs at once.
Step 1: Parts Needed
You will need the following parts:
A breadboard
An Arduino board
USB Cable
4 Jumper Wires
The RGB LED module
Step 2: Connecting the Module
Plug in the module in your breadboard, I'm using a mini one. We need to connect 4 pins - one for common ground (GND) and one for each of the 3 basic colors - red, green, blue.
GND of the module goes to GND of the Arduino. The following 3 pins are as follows:
Red (R) -> Pin 8
Green (G) -> Pin 10
Blue (B) -> Pin 12
* You can change the pin numbers in the code that I've provided below
Step 3: Uploading the Code
Connect the board to your PC using the USB cable. The code that I've written changes every color's value (from 0 to 255) so the 3 colors are random, making up the one that is visible random as well. Feel free to change the different values in the code so you can get fixed colors. By default, the color is being changed every 500 ms (1/2 second), you can change that as well
