Arduino Advent Calendar Day 06 - RGB LEDs
Today we're going to learn about RGB (Red, Green, Blue) LEDs.
An RGB LED might look similar to the LEDs we've used previously, but inside RGB LEDs, you'll find three LEDs inside!
Our RGB LED has four leads, one for each of the colours and another for a common negative connection (the cathode).
The pinout from left to right is Red, Cathode, Green, Blue.
We can make the LED shine Red, Green and Blue by individually powering their respective channels, but more excitingly, we can make a multitude of other colours by mixing these three primary colours.
Let's check out how in today's guide!
We're happy to help!
