Just a quickie this one. Dave Featherston has taken a Pi, a couple of stepper motors (with driver boards), some wood, some toothpicks and some straws, soldered up a couple of bits of perfboard, added a buzzer and created this rather neat level crossing.
I didn’t think anyone would really watch the video or comment on it. Thanks!
If anyone else is interested in building this the Python code is available on GitHub

Cheers Dave 🙂
