LED
The board also has multiple ways for you to illuminate the object that you are trying to measure for a more accurate
spectroscopy reading. There is an onboard, 5700K LED that has been picked out specifically for this task. However, if
you aren’t satisfied with the onboard LED, you can grab your own through hole incandescent. While you should find a
bulb rated for 3.3V, a bulb rated for higher voltage, like 5V, will still work, but will not run as bright as it normally would
with 5V. We’ve found that Mouser is a good place to look for these. If you are going to go that route and use your own
bulb, be sure to disable the onboard LED by removing the solder from the JP4 jumper.
