Mario can take his train set on the road with him because he build the thing inside of a suitcase. That in itself is pretty neat, but he pulled off more than just laying down a ring of track and surrounding it with realistic scenery. This train set is automated.
The suitcase itself looks a bit funny and that’s because it started as a portable phonograph. Removing the turntable and it’s requisite parts made plenty of room for the N-scale railroad (that’s really small stuff!). An Arduino with a motor shield drives the train around the loop. A reed sensor below a section of track provides feedback on where the locomotive is in the circuit. When it reaches that point the train stops and a bridge is lowered over the track for some invisible traffic to cross. There is even some audio flair which can be heard in the video after the break. It includes the whistle of the train and the ding of that bell mounted on the top half of the case.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
