Automation of Lego Duplo railroad crossing.
The idea to automate this came to me when my son plays with his Duplo train. Every time the train is about to pass a crossing, he runs to the crossing, makes the signal bell sound "ding-ding-ding-ding.." and lowers the barriers, so I decided to automate this.
After sourcing the net for small enough servos that could be built in a 2x2 Duplo brik, and 30+ 3d models/prints, I'm starting to get it working.
I will release all the 3d models and the Arduino code once I feel I have a fully working version. Stay tuned!
