[HARD] Keyes 3W LED module

tl;dr: Documenting our way through a box of Arduino electronics, one module at a time.

Pin connections

• + goes to your Arduino +5V pin.
• G goes to your Arduino Ground pin.
• S goes to an Arduino digital pin.

Once wired and powered, use like a basic LED. Example sketches Blink and Fade work well with it - the module will actually shine nice and bright directly from the Arduino’s 5V pin.

This LED module packs a serious punch: the box describes it as a 3W LED, which is a simple way to say “don’t stare at it directly in the face or you’ll get light spots in your eyes for a few minutes”. Bee tried, didn’t like it, then found the manufacturer documentation rating this LED module’s light output at anywhere between 180 and 200 lumens.

We were able to power the module from a benchtop power supply....Once, then never again. The power supply still works, the power leads still work, the LED module still works - but it just won’t draw power from the supply for some reason!
