The HC-SR04 ultrasonic sensor uses SONAR to determine the distance of an object just like the bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy ...

The transmitter uses an ultrasonic distance measurement (UDM) sensor (HC-SR04), an Arduino Nano board as the microcontroller unit (MCU), and a wireless UART RF transceiver module (HC-12). The receiver ...

All you generally need is the Arduino IDE, which already includes most of the popular libraries for interfacing with frequently used components like ultrasonic sensors and LCD modules.

It features over 5,400 projects, ranging from simple tutorials — like using a soil moisture sensor with Arduino — to more complete guides like building a Bluetooth-controlled car.

This project combines Arduino and Processing to create a radar-like visualization of distance measurements. The Arduino code reads data from an ultrasonic sensor and a servo motor, while the ...
