FUNCTIONAL DESCRIPTION: DOIT ESP8266-12E Wi-Fi Module
• This module does not have complex circuitry or programming so using this module is very easy. We will construct a simple application circuit for understanding the module working.
• Connect positive +3.3V power to the module.
• Interface module to a microcontroller or ARDUINO using UART (Connect RXD of ESP to RXD of µC & TXD of ESP to TXD of µC).
• Download the libraries for the module from the internet. For ARDUINO, the IDE will have pre-installed libraries. If you do not have them just update the libraries from ARDUINO website.
• Write the program for setting up the baud rate and data exchange.
