1/40 scale traffic light

This takes 5mm leds which push through from inside.
They are then wired and the wires run down the pole.
There is room for resistors in the head is needed.
The head needs to be glued onto the pole with some model glue and left to cure , depending on the type of glue used.
5S Uv cure glue for those making a day project out of this.
The back is a good fit and a few spots of glue will retain it.
So print as shown in the slicer preview and assemble.
For the print shown it was a 3 hour print and I used 23 grams of Pla

Hook up to a micro with some code, 560 ohm resistors and enjoy playing.
I had an esp32 at arm's length, hence the io pin numbers used.
Alter those to suit your micro being used.

Blink

Turns an LED on for one second, then off for one second, repeatedly.

Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of w
