4. About the ESP8266
• The ESP8266 is a $4 (up to $10) Wi-Fi module. It allows you to control inputs
and outputs as you would do with an Arduino, but it comes with Wi-Fi.
• So, it is great for home automation/internet of things applications.
• So what can you do with this low cost module?
 create a web server
 send HTTP requests
 control outputs
 read inputs and interrupts
 send emails
 post tweets
