Example Project - South Africa Context
A Cape Town university team used the UNO R4 WiFi to create a remote weather logger: 5V sensors and a DHT22 module connect to the analog/digital pins, while WiFi uploads readings to a cloud dashboard. Power was supplied via a USB-C adapter (5V 2A) from Communica, ensuring reliability in variable mains environments. All major components (board, sensors, PSU, cables) were sourced from local stock for rapid prototyping and technical assurance.
