Layman’s RGB LED module is an ultra-simple project realized without any ... equalized in order to match LED performance over the operating range. These ballast resistors are used in the prototype; RR ...

In a recent post we interfaced a small DMX RGB LED Par Light with an Arduino Uno through a MAX485 module ... You can see two 4.7KΩ resistors on the A&B differential lines on the module. These bias ...

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. User interface for the handheld device is ...

Neopixels, or WS2812Bs, are addressable RGB LEDs , which can be controlled individually by a microcontroller, in this case, an Arduino. The fabric was quilted with a spiral of numbers (3. ...

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.
