If you want inspiration for what you can do with an Arduino, take a look at the ten projects chosen as the winners of the Arduino Day Challenge.



The Arduino family of single board computers are very popular with hobbyists and Arduino has a very strong community. Arduino Day is Arduino's official birthday when the community celebrates its achievements. So when the call went out for fun, creative and innovative Arduino projects to compete for prizes comprising Arduino boards and other hardware goodies to a value of around €250 EUR/$280 USD, there were over 170 entries.

The winners were announced on the official Arduino Day livestream with each project having less than 30 seconds in which to show off its features. This short clip, taken from the event coverage, which is over 3 hours in its entirety and can be view here, includes all of them.

The philosophy behind the choice of winning projects was: 

Creativity is the fuel that motivates our users to experiment, build amazing projects, push the boundaries of open-source hardware and software and have a positive impact on people’s lives.

It is also interesting to note that at least half the winners were aged between 13 and 17.

The list of winning projects starts with a  smart, keyless door lock created using an Arduino Uno with a fingerprint sensor module by Anvesh Pathak. The judges comment:

A great project that has very clear, and desirable, applications. It doesn’t necessarily have to be for an external door either. This would work just as well on a cupboard, garage or even a locked box.

My personal favorite is Project Seismon from Swara Kadam whose tabletop robot is designed to help schools detect and respond to earthquakes with both warnings and preparatory drills.



The IoT High Tech Mini Greenhouse from Majiej Gala employs a lighting system as well as soil sensors making it effective and attractive and when it comes to an everyday problem solving project the Smart Trash Can, a remote contactless trash can lid powered with an Arduino Uno build by Carmen Cheung is, to quote the judges, "just a brilliant practical idea".


Another final mention goes to the Gear Machine from James Clarke powered by an Arduino Micro that provides great way to learn about the mechanics of gears, as well as how to drive them.

See the Arduino blog report for the rest of the winning entries.
