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 ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Arduino is a very popular open-source platform and Arduino UNO is one of the most loved microcontrollers among electronics hobbyists worldwide. It consists of a physical programmable circuit board and ...

Abstract: An advanced blind assistance device integrates an ultrasonic sensor, Arduino UNO board, buzzer, and GSM module to create a cost-effective solution for enhancing the safety and autonomy of ...
