Build a Wi-Fi Weather Dashboard with the Arduino UNO R4 and Visual Micro, with a Portable Solution so you're running in minutes...

Turn your Arduino UNO R4 WiFi into a live weather display - and see professional debugging in action with Visual Micro for Visual Studio.

In this episode, we create a scrolling weather dashboard that fetches real-time data from WeatherAPI.com and displays it on the UNO R4’s built-in LED matrix.

No sensors. No shields. Just Wi-Fi, JSON, and Visual Studio debugging.

You’ll learn how to:
✅ Connect your UNO R4 WiFi to the internet
✅ Parse JSON responses using ArduinoJson
✅ Display dynamic text using ArduinoGraphics
✅ Set breakpoints, tracepoints, and watch variables in Visual Micro
✅ Use Visual Studio to step through your Arduino code - live

Whether you’re a teacher demonstrating IoT concepts, or a maker building your first connected project, this is the perfect place to start.

🧰 What You Need:
✅ Arduino UNO R4 WiFi
✅ Visual Studio + Visual Micro Extension
✅ Free API key from WeatherAPI.com
✅ All Libraries and the Board Package are included in the Portable Solution!

🧠 Topics Covered:
IoT & API basics
JSON parsing in Arduino
Live debugging in Visual Studio
Scrolling text on the LED matrix
Classroom + maker project ideas
