A DIY digital Arduino clock designed for and by teachers
Arduino Team — June 13th, 2016
Project-based lessons are a great way to introduce students to the world of electronics. Clearly Jenna Debois agrees, as she has built a DIY classroom clock based on an Arduino Nano. What’s even cooler is that it’s optimized for teachers!
The device is made using laser-cut wood pieces, NeoPixels, a real-time clock module, and packs plenty of customizable features like:
An additional digit that keeps track of the block or period- an especially useful feature for rotating block schedules
The ability to program holidays into the code to prevent the block from advancing on days when school is not in session
LED digits that fade from green to red as the end of the period or block approaches so that a single glance can convey the remaining class time
A countdown timer triggered 6 minutes before the period ends that flashes between the time and the remaining time- a useful feature for signaling cleanup time
Other light effects that can be triggered during lunch, free periods, after school, or other special occasions
Debois not only created a step-by-step guide, but also shared all the documentation on GitHub and a detailed video of the build process.
