Building a controller for tiny Z scale model trains
Arduino Team — March 16th, 2026 Electric model trains are brilliant in their simplicity. The locomotives have little electric motors and the rails on the tracks act as wires to get power to those motors. But as is always the case with electric motors, there are varying levels of sophistication when it comes to speed control. To upgrade his ancient Z scale model train set, Clem Mayer from element14 Presents built this high-quality controller. Model...
