Gather the Parts and Tools

The parts needed are:

1 X 9 Volt Battery Snap
1 X Flashing RGB LED
1 X 470 ohm Resistor (not required at the moment since a compatible resistor is included with the purchase of the LED)
1X LED Mounting Board
1 X 6mm Heat shrink

Tools Needed:

Soldering Iron & Solder
Hot Air Gun
Side Cutters

Solder in the Resistor

Insert the resistor in the R1 location and solder it in place.

Solder in RGB LED

The LED is polarity sensitive. The short lead goes into the #5 hole, the long lead goes into the #6 hole. Solder it in place and clip the leads.

Wire in the 9 Volt Battery Snap

The black lead of the battery snap goes to the #3 hole, the red lead goes to the #2 hole. Solder it in place.

Add the Optional Heat Shrink

If you want to dress up the bare LED mounting board you can cut some heat shrink and heat it over the assembly. Be careful not to heat the LED.

Have Fun With the Cool Color Changing RGB Lights

Now plug it into a 9 volt battery and have some fun. Watch the video in the intro to see what it should look like when you are done.
