Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

This is a great way to use an LED strip that would have otherwise gone to waste. If you can’t find a scanner with a color wand like this one, you can always start with an RGB strip.

Inside the is a Rainboduino: an Arduino compatible board capable of driving an 8×8 RGB LED matrix. Also stuffed inside the busy box is a 9V battery, rocker switch for the power, and four arcade ...

This Arduino project allows you to mix colors using three potentiometers and control the timing/delay of color transitions using a light sensor (LDR). The RGB LED’s color intensity is set by the ...

Arduino RGB Button Control This is an Arduino project that controls RGB LEDs using push buttons. Each button controls one LED color (Red, Green, or Blue). When a button is pressed, the corresponding ...

Our RGB matricies are dazzling, with their hundreds or even thousands of individual RGB LEDs. Compared to NeoPixels, they’ve got great density, power usage and the price-per-LED can’t be beat.

Guadagnini et al. (33) built a photometer consisting of a red LED (wavelength 620 nm), a BH1750 sensor, controlled by an Arduino NANO, showing applications for absorbance measurements in CuSO 4. dos ...
