This 8 rgb led module is 3.43 on sale now from icstation but you can use my coupon code “icsJoey” for an additional 15% off. It took me FOREVER to find any information about this since it wasn’t posted anywhere but here it goes:

The RGB pins go to ground depending on the color.

D0-D7 go to corresponding pins on arduino depending on which lights you want to light up.

Connect RGB to pin 9, 10, and 11 on your arduino and pins D0-D6 to pins 2-8 and D7 to pin 12

Connect +5v on arduino to VCC on the board

Upload the following code:
