Introduction In the world of DIY electronics and robotics, the Arduino platform is a favorit choice for enthusiasts, hobbyists, and proffessionals. Within its versatility and ease of use, Arduino is the ideal platform for creating innovative projects, and one popular application is object distance detection using an Ultrasonic HC-SR04 sensor. In this blog, we'll guide you through the process of building an Arduino project that can accurately measure distance using this sensor. What You'll Need Before we dive into the project, let's gather the necessary components: Arduino Board Ultrasonic HC-SR04 sensor. Jumper Wires. A power source for your Arduino. Some object to test your distance detection. Understanding the HC-SR04 sensor The HC-Sr04 sensor uses ultrasonic waves to measure distance. It has two main components: Ultrasonic Transmitter: This component sends out a high-frequency sound wave that bounds off object in its...
