English: Code to measure distances using an ultrasonic sensor connected to pins 9 (trigger) and 8 (echo) on the Arduino Uno. The distance is calculated in centimeters and inches, and displayed on the ...

HC-SR 04 Ultrasonic sensor is most commonly used to measure distance, but this time I will show you how to measure the speed of movement of an object using this sensor. Device is very simple and ...

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.

Build a Bidirectional Visitor Counter using Arduino and IR sensors to track entry and exit movements with real-time counting on an LCD display. This step-by-step guide covers circuit design, hardware ...

The design was prototyped using an Arduino, which controlled an LED through feedback from an ultrasonic proximity sensor. The LED would flash into the user’s peripheral vision, glowing when the sensor ...

Producing items onto a screen simply by touching the air is a marvelous thing. One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a ...
