In this hands-on tutorial, I'll show you how to build a working AI-powered person detector using the Arduino Uno Q. By the end, you'll have an application that uses a USB webcam to detect people in real-time and displays the results on the built-in LED matrix.
More importantly, you'll understand what makes the Uno Q unique: its dual-brain architecture, how Python and Arduino code communicate through the Bridge, and how Bricks make AI development surprisingly accessible.

🔧 KEY CONCEPTS COVERED:
• Dual-brain architecture: Qualcomm Dragonwing (Linux) + STM32 (Arduino)
• The Bridge: How Python calls Arduino functions
• Bricks: Pre-packaged AI modules running as Docker containers
• App Lab: Unified development environment
• Project structure: Python, Sketch, Assets, and app.yaml
• Command line access and Arduino CLI
đź”— USEFUL LINKS:
• Arduino Uno Q Official Store: store.arduino.cc/products/uno-q
• Arduino Uno Q Documentation: docs.arduino.cc/hardware/uno-q
• Edge Impulse (custom AI models): edgeimpulse.com
⚠️ HONEST NOTES:
This tutorial shows both the potential and the current limitations of the platform. App Lab (v0.3.x) is still under heavy development—expect some rough edges, occasional crashes, and connection quirks. The 2GB RAM can feel constrained when running Docker containers and AI models. That said, I was able to get a working AI application running with relatively little effort.

![[160] Arduino Getting Started: Digital input and button](https://i.ytimg.com/vi/RK8kM8LW2Oo/mqdefault.jpg "[160] Arduino Getting Started: Digital input and button
This tutorial introduces how to integrate a push button into your Arduino projects to control an LED. Using a digital input pin, youll learn to read the state of the button and use its status to turn an LED on and off. This project builds on our previous tutorial by adding a push button and demonstrating how to set up and code for interactive elements. Through the demonstration, youll understand how to handle button states and debouncing, enhancing the interactive capabilities of your Arduino projects.
