RGB LED Strip Dimmer with 555 Timer

In this Instructable, I’ll be showing you how to make a cool RGB LED strip dimmer using a few potentiometers and a couple of 555 timers. I’m currently working on a larger project which involves using this circuit, but I thought it would be good to share this circuit since it’s really cool to play with just by itself. The larger project I’m working on is comprised of two circuits: the RGB dimmer and a colour organ which makes the LEDs dance to the music when an audio source is plugged into the circuit. I was inspired to work on this project after posting this Instructable here which used a single colour LED strip with a dimmer and an audio pulsing circuit. After posting this, I received many comments and messages requesting to work on an RGB version of the circuit, so here is part of it, with the rest to follow very shortly.”
