Light Parts

This is a list of parts used in building this repository, and a few more that might be useful.

Programmable LEDs (WS2812b, SK6812, APA102C or equivalent):

LED Strips (not individually addressable):

DC power supplies:

Connectors:

LED standard-base 12V bulbs (G6.35 2-pin base):

Components

Transistors. For most 12-24V sources, you’ll need transistors to control them from a microcontroller. The following transistors have been tested with the examples here:

Tangible controls. These are included for example purposes only. You can use whatever input you want for your LED projects.

Microcontrollers

I tend to use the MKR series Arduinos a lot:

Spectrometers

The AS7341 is an 11-channel spectral sensor that can detect light levels in multiple frequencies from around 400nm to 900nm. It has 8 that sense light in visible spectrum; one channel in the near infrared spectrum; one clear channel without a filter; and one channel that detects 50Hz-60Hz light flicker.
