In this tutorial we use SPI Protocol for communication between two Arduinos. Here one Arduino will act as Master and another one will act as Slave, two LEDs and push buttons will be connected to both ...

Here in this project, we will be demonstrating Li-Fi communication using two Arduino. Here the text data is transmitted using LED and 4x4 keypad. And it is decoded on the receiver side using LDR.

Demonstrates a simple TCP/IP Link enabling two Arduino's to talk to each other using the extremely cheap and versatile ESP8266 Wifi modules using SoftwareSerial and AT commands. Either of the setups ...

This repository contains a collection of example codes demonstrating how to use WiFi with Arduino, focusing primarily on ESP8266 and ESP32 modules. These examples are designed to help users explore ...

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.

Data transmission through wireless medium has been prominently increasing in the current era due to many emerging technologies like Internet of Things (IoT). Most of the wireless communications happen ...

The Arduino UNO R4 Minima and the Arduino UNO R4 WiFi. But apart from the obvious wireless connectivity hinted by the name what other differences do the microcontrollers have.
