Esp8266 basics
This document provides an introduction to programming the ESP8266 WiFi chip. It outlines ESP8266 basics, including an overview of the ESP-01 and ESP-12 models. It then demonstrates how to connect an ESP8266 to an Arduino and use the Blynk app and library to control an LED over WiFi. Wiring diagrams and code examples are provided to showcase setting up and programming the ESP8266 for basic WiFi functionality and Blynk integration.
