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 ...

Here we discussed about the pinout and different modes of ultrasonic sensor module and how it works. Also we learned how we can use ultrasonic sensor module with Arduino.

The complete Arduino Levitation circuit is shown below and the working principle of the circuit is very simple. The main component of this project is an Arduino, L239D motor driving IC, and ultrasonic ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

Arduino UNO circuit board [8] and an HC-SR04 ultrasonic distance sensor [9] were used for data collection and are shown in Figure 2. Arduino UNO was placed on upper face of top plate and ultrasonic ...
