Too much power draw from an Arduino problem

Hi, you need power transistors to drive the big LED strings from Arduino.

Example: http://goo.gl/K7Y6h (See the schematic there if you want to build your own)..

Also, "Motor Drivers" are really multi-channel power drivers and can drive LEDs...

See "Arduino POWER" on the Arduino-Info WIKI here: http://arduino-info.wikispaces.com/ArduinoPower#DC
