Arduino Uno (or other compatible models): The heart of the project, responsible for controlling the SONAR system. Connecting Wires: Essential for connecting various components together on the ...

The HC-SR04 sonar modules are available for a mere pittance and, with some coaxing, can do a pretty decent job of helping your robot measure the distance to the nearest wall. But when sellers on eB… ...

The Plan The plan is to take an inexpensive SONAR module (the HC-SR04) and an Arduino Leonardo and use it to perform some simple tasks by mimicking keyboard input from the user.

Circuit Diagram: Description: The Arduino Sonar project integrates an ultrasonic distance sensor and a servo motor controlled by an Arduino UNO R3. The ultrasonic sensor measures distances, and the ...

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...
