RGB LED Test Perfboard
This is the schematic/circut for the perfboard pic I posted earlier. It controls a common cathode RGB LED using three transistors. Thus, it works great with microprocessors (like the Arduino), allowing one to control the intensity of the three colors using PWM (pulse width modulation) to create any color. See the note for the simple parts list. If you have any questions, post a comment.
