This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

The ultrasonic sensor uses sonar to determine the distance to an object. Here’s what happens: The ultrasound transmitter (trig pin) emits a high-frequency sound (40 kHz). The sound travels through the ...

Ultrasonic sensor powered by Arduino UNO The servos should not be powered by the Arduino directly due to insufficient current supply, which could damage the voltage regulator. Instead, an external ...

The ultrasonic sensor with Arduino allows us to measure distances through ultrasound. It is very common to find this type of sensor in today’s cars. The objective is to show how we can build real ...

In this project, the ultrasonic sensor module type KY-050 is used together with an Arduino and a type KY-012 active buzzer to help while reverse parking our vehicle.
