About This Class


This project introduces you to the HC-SR04 Ultrasonic Sensor. We will be creating an alarm circuit with a buzzer and warning LEDs. You will understand how an ultrasonic sensor works and how to interact with it in code. This is a very handy addition to your Arduino electronics projects for obstacle avoidance.

Learning Objectives:

  • How an ultrasonic sensor (HC-SR04) works
  • The pinouts and how to connect an ultrasonic sensor in a circuit
  • How the pulseIn() function works
