Programming sensors using Arduino

Programming sensors using Arduino

This is a practical Arduino guide designed to support teaching and learning in introductory electronics, physical computing, and STEM-based project work. It provides step-by-step instructions for integrating multiple components—including an LED, DHT22 temperature and humidity sensor, buzzer, ultrasonic sensor (HC-SR04), and load cell—into a single applied project. The resource includes a full circuit diagram, annotated wiring guidance, example Arduino code, and discussion of real-world applications and common troubleshooting challenges.
