Four Bc337 transistors to power the LED's. The current per color is 40mA, so I had to use these to not kill the Arduino outputs.
Here a small color test with the dot pattern.
And this will be the first test setup to control the LED's
A project log for P.C.M. Mask
How To Hack Your Brain :). The main Idea is to control different led pattern with my pulse while listening to relaxing music.
