Seperate your wagons from your locomotive using this awesome Arduino-powered decoupler!
Using a single motor and some infra-red sensors, this clever construction of gears, axles and plates can block one side of the track, preventing individual rolling stock from moving forward. From there, just power your train forward to uncouple your wagons!
This tutorial incorporates the decoupler into a siding, allowing you to uncouple wagons, switch points, then retrieve other wagons before continuing on your journey. All the code you need for your Arduino is provided, including a full explanation of how the decoupler is build and configured.
Contains vintage 9V Lego train sets 4565, 4544, 4552, 2126, 4536, and 4537.
