State diagram

Intro to Digital I/O and State Machines

This is lab 3 of 10 in the course

Learn state machines and digital input and output by creating a working traffic light. Students learn about state diagrams and how these are implemented in state machines in a Virtual Instrument. They use this concept to control one LED, and then expand it to create a model of a stop light with LEDs. The challenge exercise has students add logic for a walk timer to their code.
