In this exciting hands-on project, students will build a Smart Dustbin that opens automatically when someone comes close, just like modern touchless bins found in malls, airports, and hospitals. Using the Calliope Mini and an ultrasonic distance sensor, learners will understand how sensors detect objects, how actuators respond, and how code controls real-world actions. This […]

In this project, you will learn how to measure temperature using a DHT11 temperature and humidity sensor and control a fan using a 3V relay. You will understand how sensors provide data to microcontrollers, and how actuators like motors respond to conditions. Using the Calliope Mini V3, you will gain hands-on experience with wiring, coding, […]
