So, here we provide an example of how to use the HC-SR04 ultrasonic sensor with the Arduino. In this project, the ultrasonic sensor reads and writes the distance to an object in the serial monitor. The goal of this project is to help you understand how this sensor works. Then, you ...
By eliminating one I/O pin requirement we can save a connection to our Arduino and use it for something else. It also is useful when using a chip like the ATtiny85 which has a limited number of I/O pins. Here is how I hooked up the HC-SR04 to the Arduino. As you can see all ...
