This course is a strong foundation for understanding IoT utilizing wireless Arduino communications.  We will be using both the Arduino and the ESP8266 for wiFi and radio functions.  This course will give students an good understanding of IoT and wireless communications utilizing Arduino and the ESP8266 with inexpensive wireless transmitters, receivers and transceivers. We will go over most of the popular and least expensive methods, tools, and associated hardware to pass data wirelessly between devices and over the web and through the cloud. Students will learn how to configure, develop, and program these popular and cheap wireless devices to trigger an event or pass data between devices. Students will be able to thoroughly grasp the concepts of transmitting data around the web:

*ESP8266 to the web

*Between Arduinos

* Arduino data to a PC

* Arduino data to the “Cloud”

* Arduino to Putty and Teraterm

* Arduino to SD Card for Datalogging
