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 ...

A minimal example that reads a digital IR (obstacle/proximity) sensor on pin D2 and lights the onboard LED (pin 13) when an object is detected. The project is configured to build with PlatformIO for ...

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 ...

Abstract: Aim: The objective of this work is to control load at home using Arduino IDE with DHT11 sensor and comparing its temperature performance with microcontroller device. Materials and Methods: ...
