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 ...

Human Following Robot Using Arduino Code. Here is a simple 3 Ultrasonic sensor-based Human following robot using Arduino Uno code that you can use for your project. This code reads the distances from ...

1 Arduino Ultrasonic Sensor (HC-SR04) 1 buzzer; Ultrasonic sensor, mounting circuit; It is a very simple circuit. On the one hand, we will have all the alerts, acoustic and visual, and on the other ...

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.

The quick road test, oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use this sensor (or its latest version) in a more complex project in the next ...
