Hey Everyone,

New to the forum, looking for circuit ideas to control 28 5050 RGB LED's. I am wanting to be able to control each Led individually and be able to make patterns, similar to how these led strips work https://www.adafruit.com/product/1138 . My first thought was to use Arduino to control them due to the simplicity, but i am pretty new to electronics and have to idea how to work and wire anything. Thanks in advance for your help!

Sincerely,

Logan

Most basic 5050 LED strips are wired like the below drawing of a single section where each section contains three individual RGB LEDs.

The sections can be cut down and trimmed using a good razor knife or Exacto knife as seen below.RGB Strip.png

The first image also shows some MOSFETs (FQP30N06) used for driving the LED strings by color Red, Green and Blue. The MOSFETs used cost about $1.00 each from any of several online retailers. Beyond R, G, and B other colors are made using a mix of R, G and B.Just as an example with all on we would get white, with only Red & Green we would get Yellow.

Using an Arduino is really quite easy because there are literally hundreds of code samples out there which can be a copy and paste. With a little work you begin to see and understand what the code is doing and will start writing your own code for the effects (results) that you want.
