We completed the WiFi light switch project successfully but would like to understand how the ESP8266 chip works with Arduino ? I have a spare ESP8266 chip and would like to do a simple project (turn on an LED using wifi control). Can someone help me get started on this ? What do I need (voltage regulator, mosfets etc) and how to connect it on a breadboard ? Could I use the TX/RX pin on Arduino or do I have to use the Analog pins as in the WiFi light switch project ?
It would also be great if there are some simple breadboard project with these kits to understand how to connect and use the chip with Arduino before heading to the PCB. It’s hard to figure out the PCB connection after soldering and sometimes schematic is also not very simple to understand with so many components. I would be able to create my own project someday if I understood how the ESP8266 works and what else do I need with it to connect to Arduino.
