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 ...

TK introduces us to the ESP-01 modules and shows us how to get started with a simple serial adapter and and the Arduino IDE. You will be up and running in less than an evening.

Este projeto transforma um ESP8266 ESP-01 em um dispositivo IoT que controla um botão físico e envia seu estado (ON/OFF) para o Home Assistant via MQTT. A cada pressionamento do botão, o estado é ...

A lot of people have used ESP8266 to add inexpensive WiFi connectivity to their projects, but [Oscar] decided to take it one step further and program an Arduino over WiFi with the ESP8266.

Sweet! That turns this into an Arduino compatible board which solves something that has long bothered me. I’ve seen a ton of really simple Arduino projects that use the ESP8266 externally.

The ESP Offline Programmer is an ESP32 board with a microSD card slot designed to flash the firmware to other ESP32 or ESP8266 modules without a PC.
