An RGB LED module is a versatile lighting component that can produce millions of colours by mixing red, green, and blue light ...

Perhaps one of the most common modules in an Arduino starter kit, the RGB LED lets you create all sorts of colors with just four pins from the Arduino. This tutorial demonstrates two ways to use this ...

analogWrite(redPin, leds[(k + 120) % 360]); // Set 120deg relative phase for red LED analogWrite(greenPin, leds[k % 360]); // No phase shift for green analogWrite ...

Supports with RGB_LED version 1.1.3 or higher. Configure your PIN out for RGB LED data for WS2812b. Now it's D4.

The circuit diagram shows the connection between all the electronic components and Arduino Nano. Also check various NeoPixel LED based projects by following the link.

Here is a 3D light show that will astound you with its combinations. Inexpensive and easy to make thanks to an Arduino controller, the design enables you to play with the existing effects and, most ...

I’ve seen the concept art for “real world eyedroppers” several times. I haven’t noticed any of the products come to market though. It isn’t the technology stoping them, color sampling can be done a ...

Arduino has announced a Linux-capable version of its Uno, called Uno Q and based on a pair of processors: the quad 2GHz Arm Cortex-A53 QRB2210 from Qualcomm for the operating system, and the 160MHz ...
