This common pin is either the anode (positive), or the cathode (ground) of each LED. It is better to use a common cathode “diffused” RGB LED here because the diffused lens helps blend the colors (with ...

The Arduino-compatible lighting RGB LED lighting shield reviewed here was designed to give designers a low-cost easy-to-use open-source platform for fast prototyping and inexpensive evaluation of ...

For prototyping, Infineon has a RGB LED lighting control shield for Arduino, based around its ARM Cortex-M0 XMC1202 microcontroller. On board is something called a ‘brightness colour control unit’ ...
