The firs scetces I did were simple one liner color set methods.

I tried diferent colors and brightnesses to see how bright it would be with just the usb power.

In theory each led uses 100mA, I have 200 leds wich equates to 30A! of power usage. So I will ad a bigger power supply later.

Old Pc power supplies are great for this application as they can proivide up to about 40A on the 5V rail.
