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 buy an ...

Arduino enthusiasts may be interested in a new single pixel scanning camera which is powered by an Arduino Uno combined with a TCS34725 sensor available from online stores such as Adafruit. Created by ...

Please be aware that the code works under the assumption that you have the SmartLightBulbLibrary library, which offers functions for controlling the smart light bulb. Replace it with the proper code ...

This system uses a colour-changing LED (RGB LED/tri-colour LED) that switches to a new colour every 5 seconds. Simultaneously, the colour name is displayed on an OLED mini screen (SSD1306). This ...

A pet project built to explore how a browser-based UI can communicate with physical hardware in real time. The idea was simple: pick a color on screen and have an RGB LED reproduce it instantly — no ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...
