In this course, students learn to create sophisticated Arduino projects that utilize a range of sensors and components. Beginning with a review of basic circuits and Arduino functionality, the course progresses to hands-on applications using sensors like temperature and humidity, tilt, touch, and infrared, among others. Students will learn to program complex functionalities, such as controlling an RGB LED with a push button, measuring distance with an ultrasonic sensor, and setting up a shock sensor with an LCD display. Through each lesson, students will develop the skills to connect, code, and calibrate sensors, allowing them to create highly responsive and interactive projects. By the end of this course, students will have gained the expertise to design advanced Arduino-based systems, bridging the gap between programming and physical electronics.
