Arduino code for detecting basic hand gestures using HC-SR04 ultrasonic distance sensor array. This code utilizes three HC-SR04 ultrasonic distance sensor modules placed linearly with a fixed distance ...

This project demonstrates how to use an ultrasonic distance sensor (JSN-SR04T) with an ESP32 to measure and display the distance on an SH1106 OLED screen using UART communication. Connect the SH1106 ...

Ultrasonic sensors are used to detect the presence of obstacles, calculate the distance to these obstacles, and relay this information to the driver through visual and auditory cues. This research ...
