Lorraine hacks a Bluetooth-controlled LEGO train in this week’s episode of element14 Presents, mounting a track system to the ceiling of her home. She integrates CircuitPython, a Seeed XIAO board, NeoPixels, and a spinning LIDAR sensor to detect walls and control the train’s movement. The video covers setup, track planning, component integration, and a ground-level test before moving the build to its final ceiling-mounted location.
