2021 Update: since this article was originally published, we have introduced our own Arduino Shield, which has built-in MOSFETs for controlling hundreds of lights.  Using the shield is the quickest, easiest way to use our lights with Arduino.

Since Brickstuff LEDs operate on 5V DC, they are directly compatible with 5V Arduino boards.  The attached document shows some ways in which LEDs can be connected to an Arduino board (the board shown is the Uno, but any 5V Arduino-compatible board will work the same way).

The attached document shows cutting/splicing of Brickstuff cables, but if you prefer cleaner connections, you can use our DIY cables (available in packs of 5) which have bare wires on one end and a standard Brickstuff connector on the other end.
