Easy traffic lights for Lego worlds with Arduino

The synergy that can be found with Lego and Arduino is almost infinite, such as the CD duplicator system reviewed previously. However in this example ‘Maloffstrano’ has built automated traffic lights for a Lego traffic intersection that are life-like and blend completely into the fictional world. Using a tiny Arduino-compatible board and some repurposed Christmas tree lights, the results have been quite successful:


It’s good to see how well Lego lends itself to the use of LEDs, wiring and therefore our projects. For more information, the design and code visit here. To get started with your own Arduino-embedded Lego projects – use the Freetronics Leostick. It’s one of the smallest Arduino-compatibles on the market with USB, an RGB LED and piezo for sound effects:
