Add colour to your project by controlling 16 red, 16 green and 16 blue LEDs with just 3 pins of your microcontroller. The RGB MATRIX uses shift registers, a matrix and switching transistors, so there’s plenty to learn and explore.

SKU: BRM001 Category:


The RGB MATRIX uses 3 or 4 pins from the MOTHERBOARD to control 2 HC595 Shift Registers, which in turn, switch Transistors which sink and source current for the 16 Red, Green and Blue LEDs. With some crafty programming, these could show simple animations or even some PWM powered rainbow or lava effects. These can be used as coloured reminder lights: Flash blue to remind you to drink water, or flash red when you need to call your mum… Or you could program them to show you a representation of the temperature or humidity using the SENSOR BOARD, or a coloured sound meter to help you keep your sax playing to a reasonable level. You could also use one for under-glow lighting or to light up the inside of The Cube.
