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.

Arduino RGB LED Controlled by 4x4 Matrix Button Hi, my name is Rahmat Hidayat. I code for fun and sometimes share my code here so I can reuse it later. Feel free to use or modify this project. If you ...

For example, the code begins by decreasing the red LED value while increasing the green LED value. When the red LED value reaches `0`, we begin decrementing another LED (green in this case). Similarly ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can bu… ...

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.

This way we can continuously change each color. Now launch the Theremino RGB application and set First input slot - 1, Num input slots - 3 and First output slot - 9. When dragging the sliders up and ...

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 ...

While we’ve seen many Raspberry Pi enclosures made out of LEGO in the past, this Portal-themed build with RGB lighting deserves a special nod. We spoke to the creator of this build, Instagram ...
