Learn how to establish a Wi-Fi communication (HTTP) between two ESP8266 NodeMCU boards to exchange data without the need to connect to the internet (you don’t need a router).

ESP8266 Wi-Fi Module is Now Supported in Arduino IDE ESP8266 revolutionized the IoT world by offering an ultra low cost Wi-Fi solution either standalone or connected to a micro-controller board via ...

Since the Wemos D1 can't directly measure internet speed like a PC, it can simulate a speed test by: Downloading a file or data from a server. Measuring the time taken. Calculating speed = size / time ...

There has been some buzz around ESP8266 Wi-Fi module, mostly because of its low price, and SDK availability, meaning it could become the Wi-Fi equivalent of ENC28J60 Ethernet module, and that for $5 ...

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.

Arduino relay shields are abundant, along with real-time clocks, and now, built-in WiFi. The tough part will be coming up with apps and web interfacing, but that's not totally necessary either.

Digilent's chipKIT WiFire board is an awesome little beastie. Powered by Microchip's latest 32-bit 200 MHz MCU, the Wi-Fi equipped Arduino-compatible platform has been paired with Imagination ...
