The Arduino chip, for example, is on a custom PCB, and all the hardware has been nicely integrated into LEGO’s closed off nine volt model train system.

I built it for the by Arduino automated Lego train container terminal that I’m currently building. This Lego compressor contains 4 Lego PF M motors, 8 Lego pneumatic pumps and 10 air tanks.

This Lego decoupler can be further improved with an Arduino, a few ultrasonic sensors, and an IR detector to make a fully automatic decoupling siding for a Lego train layout.
