A small PlatformIO/Arduino project that measures distance using an ultrasonic sensor (HC-SR04 or similar) and prints the measured distance over the serial port. This README explains how to open the ...
In this tutorial, you will learn how to send WhatsApp messages directly from an Arduino UNO R4 WiFi using the CircuitDigest Cloud Whastapp API. Instead of using a GSM module, SIM card, or complex ...
This project demonstrates how to interface an HC-SR04 ultrasonic distance sensor with an SSD1306 OLED display using the STM32 Blue Pill microcontroller. The system measures distances and displays them ...
Abstract: In this paper, we present a prototype of a miniature radar system using the ESP32 microcontroller and an HC-SR04 ultrasonic sensor. The prototype utilizes a servo motor to rotate the ...
Abstract: The paper presents a pioneering approach to revolutionizing non-touch screens into touch-enabled interfaces by leveraging ultrasonic sensor technology. The focal point of this research lies ...
