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… ...

This project utilizes an Arduino Uno, a sound sensor, and a Bluetooth module (HC-5) to create an interactive LED matrix display. The project can be controlled via a mobile application, allowing you to ...

[Fjord Carver] brings together an RGB LED and CdS Photoresistor to make a color sensor. Those Cadmium Sulfide lights sensors usually have a very wide swing of resistance when exposed to varying lev… ...

This project converts HSV (Hue, Saturation, Value) color values into RGB (Red, Green, Blue) values and displays the corresponding color using a single RGB LED connected to an Arduino board. HSV is a ...

The Arduino GIGA Display Shield is a 3.97-inch RGB touchscreen display designed for the Arduino GIGA R1 WiFi board introduced a few months ago with an STM32H7 dual-core Cortex-M7/M4 microcontroller ...

Here we describe an open-source Arduino RGB LED photometer that can be 3D printed and contains an educational interface written in Python for use in chemistry laboratories. ... Emission spectra of the ...
