You can sense a lot of things with the right sensor, and [Nikhil Nailwal] is here to show us how to sense colors using a TCS230. The project is a simple demo. It displays the color and lights up an… ...

He came up with a simple hack: colored paper attached to the scale’s dial and an Arduino with an OSEPP COLOR‑01 color sensor pointed at the paper.

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.

Researchers from the University of Johannesburg in South Africa have developed a cleaning system for solar modules based on the TCS3200 color sensor and the Arduino Uno open-source microcontroller.

Alternatively, a µC with at least three ADCs could be used. D1 adds brute-force hysteresis to the comparators, and D2 allows the Arduino to define a maximum exposure time by pulling node T2 down, ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

You can actually build your own color-sensing lamp with this $8 Adafruit RGB color sensor, and follow along with plenty of Arduino tutorials online. But look how cool and sleek its product video is!
