This project uses a $30 Arduino Uno R3, an RGB LCD display, a waterproof temperature sensor, food grade heat shrink, and a few other components, all of which are available at the link below from ...

If you’d like to get more specific, Michael Klements’ Arduino-based scanner lets you quantify colors in numerical RGB values via a TCS34725 sensor. User interface for the handheld device is ...

The board itself is very straightforward, with four MHPA1010RGBDT RGB LEDs and a couple of passives to keep them happy. The Nokia 5110 LCD module just pops right on, and beyond the extra pins ...

Neopixels, or WS2812Bs, are addressable RGB LEDs , which can be controlled individually by a microcontroller, in this case, an Arduino. The fabric was quilted with a spiral of numbers (3. ...
