The lesson that brings together the two halves of the course. Each mecano piece is given a name and a pin, just like you declare it in a program, and that number is the contract: the program speaks through it and the piece listens through it.

🎯 The challenge of this lesson

Place a servo on pin nine and an LED on pin thirteen in your mecano; then try putting another LED on pin thirteen too and see what the mecano tells you.
