Best use of Arduino Uno Q

by Arduino

The Challenge

Bring your idea to life in the physical world with Edge AI and the Arduino UNO Q.

Use the Arduino UNO Q and Modulino sensors in your hackathon project, whatever challenge you are solving. Bring Physical AI to life: run AI models directly on the device, sense the real world and make things move, light up or react.

This tech challenge is open to all teams, so you can combine it with any other Junction challenge or your own idea. Start by asking what problem you are solving and who it helps, then think about how hardware and Edge AI can make your solution tangible. The best projects combine a working physical prototype with a smart use of on-device AI.

Mentors:

You can find them from Arduino Hardware Lab and on Discord.

Insight

Arduino is also hosting the main challenge The Green European Renaissance, where teams use Edge AI and the Arduino UNO Q to create local solutions for a greener Europe. The Best Use of Arduino tech challenge is open to everyone, so teams working on any challenge can use Arduino to make their solution physical.

The award goes to the team that makes the best and most creative use of Arduino in their project, in any challenge. We focus on the following criteria: Use of Arduino hardware & Edge AI (50 %), Working prototype & demo (30 %), and Creativity (20 %).

Getting the hardware

Arduino UNO Q kits are available to borrow from the Arduino Hardware Lab. You’ll find the instructions for booking and picking up your kit here: https://2026.hackjunction.com/hardware

Submission: on Junction Platform and to Arduino Project Hub

To be eligible for prizes, you must publish your project on the Arduino Project Hub in addition to submitting it on the Junction platform, where peer review and judging take place.

Resources

Participants can use Arduino hardware and software to build Physical AI prototypes for any Junction challenge, with Arduino mentors on-site to help with technical questions. You can find the Hardware from Arduino booth.
