This repository provides a project for connecting Raspberry Pi 4 and Arduino Uno R3 via serial communication. It includes sample code for minimal serial communication between the two devices.

The table shows the pin configuration of the Arduino UNO–based robotic arm. The red (VCC) wires of all servos are connected ...

This Arduino project demonstrates how to use serial communication to interact with the user through the Serial Monitor. The program prompts the user to enter a number, and once entered, it reads the ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi with an ESP8266 ESP-01 module. With ...

When [Bill Porter] works on a project, he says that he typically writes his own NMEA standard communications protocols to fit the job at hand. While it makes things easy to troubleshoot, he admits ...

The official Arduino Blog has this week featured a new project which demonstrates ultrasonic Arduino to Arduino communication by Brazilian maker Eduardo Zola. Showing that you can communicate between ...

Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...

I like to visualize things, so I decided to prepare this simple tutorial to help you better understand how to visualize data using Arduino. This tutorial assumes that you have some basic electronics ...
