Lightbox RGBW Upgrade
2019-Sep-06, Friday 06:25 pmI'm wandering around a supermarket when I spot an A4 lightbox. The kind I see in many bars and youtube videos; backlit with white LEDs, a plastic diffuser, and slots for placing plastic tiles with letters written on them. It's a nice idea, restrained, classy. Requires 6 AA batteries. 6?! That's 9 volts. For 18 white LEDs? I needed to see what was going on inside.
( Details )
Then finally connect the RBGW LED strip up to a microcontroller, load up the example sketch, and close up the lightbox. Oooh pretty. I have this working as a rather colourful lamp off an Arduino until I can figure out how to get my Feather 32u4 Bluefruit LE working correctly. But it can run off a 3.7V battery, or USB power. Which is a considerable improvement over 6 AAs and 9V. And with so many more colour options!
*edit* Finished in part two.
