Traffic light for Brio / IKEA / alike train-tracks
Description
I made this traffic light for my son. To build it I used: 1x Arduino Nano Clone 3x 5mm LEDS 3x 200ohm resistors 1x 1kOhm resistor 1x miniservo (e.g. https://www.aliexpress.com/item/32948823768.html) 1x 6x6mm push button (e.g. https://www.aliexpress.com/item/32857436208.htm) 1x m2 8mm screw 1x m3 bolt and nut Wires & some source of battery to power the Arduino. I made this. It works perfectly, but it is still work in progress: https://www.thingiverse.com/thing:4228350 If you want to make this but need help with the code or the wiring - just let me know.
