Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...

This proposed Arduino-based automatic bell device is an electronic system that rings bells at predefined times without manual intervention.

Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

Last week, we covered the Maker Go RA4M1-R4 development board, an inexpensive “clone” of the Arduino UNO R4 Minima with some small modifications like support for up to 50V DC input and a 3.3V/5V ...

While keeping the same form factor, size and compatibility with existing Arduino Uno shields, the Arduino Uno R4 packs a very powerful Arm SoC for more advanced use cases. Previously we have done a ...

Options to power the Arduino Nano include USB, VIN, and 5 volt pin, meaning you have power options for almost any situation.

This HX711 library has an interface which is a superset of a library by Bogde. Some missing functions were added to get more info from the library. Another important difference is that this library ...

This research aims to develop an interactive learning system based on Arduino Uno basic material. To realize this system, Augmented Reality technology is used which will explain each Arduino Uno pin ...
