Attach the Driver or Resistors to the LEDs

If a LED controller is being used: 

- Construct your driver using This Instructable or One of your choosing.

- Solder the wire leads of the LED's into their correct holes on the driver.

If single Color LEDs are being used: 

- Its usually best if each LED gets its own resistor, but otherwise a single larger resistor could be used.This Calculator can be used to calculate resistor values or Contact Me 
*Auto-Change LED need their own resistor for each LED.

- Solder the resistors to the LEDs and connect them in parallel.

- Or solder all the LEDs in parallel and place the large-wattage resistor in series with V+.

Prepare the PSU: 

- For this I am using a 5v 500ma USB charger. Modifying a wall-wart style PSU as I am, is not suggested, do so at your own risk.
*Otherwise My Store has 5v @ 2A Power Supply with matching panel mount barrel jack, its would be a lot safer.

for the USB Charger:

- I removed the plug blades and replaced the wires with longer ones, blue wire in the images.

- I then soldered some dual strand 20ga speaker wire from V+ & V- to the respective holes on the driver board.
