Crosswalk Project

ECE301 - Intro. to Circuits, Summer 2019, EiL Written by Ben Sergent V
ECE301 Crosswalk

Summary

The class will use an Arduino to build a crosswalk emulator to get a feel for some electrical components and learn how microcontrollers generally work with digital circuitry. Work will be done in seven groups of three with each group finishing a stage of the project and handing off their progress to the next group. Each stage should take roughly two hours to complete.

The difficulty ratings and category assignments for each stage are meant to allow students with prior experience working with Arduinos or programming to retain interest. None of the stages are overly difficult, and even students with no prior experience will be able to do any stage, but the more difficult stages may take more than two hours to complete for less experienced students. In addition, the difficulty ratings are meant to be relative to the other stages, so a 5/5 is not impossible.

Grading

You do not have to complete the questions for each stage; they are just to help keep you on track. The graded portion of the project will be the in-class demonstration of what you accomplished.
