Many lighting project look better with a bit of colour!  Now your students can all use the same roll of LED, but pick from Red, Green or Blue.

Simple cut a length and stick to your choice of material using the sticky back adhesive.

Solder the red wire from a 5V USB cable to the '+ Volts' pad.  Students can now decide where to solder the black wire, choose from the R/G/B pads to confirm the colour choice.

These are are really bright and great fun to use for a variety of lighting projects.
