So I got my toddler this car track which has junctions in it but hes a bit young to understand them and if you dont move them when a car passes then they end up crashing.
I want to play with the arduino and somehow do some automation or even a little control box etc.
The issue is the junction is totally plastic and really only works using your hands to move it. there is no mechanical lever either.
I was thinking of playing with.... magnets or something or is this a really complex idea?
I'm quite new to arduino so i know even know what components could exist that could help me get the mechanics of moving it, but as for the code and triggers I can have a brainstorm about what I want to do there.
Thanks for any ideas!
