IoT-ALE: Reading Sensor Data with I2C

I2C is one of the most ubiquitous interconnects that processors of any scale use, from the modest ESP32, to the impressive and largest scale server grade CPUs. Commonly used with connecting to sensors, this tutorial will focus on a high level overview of I2C, the protocol, addressing, and how it differs from other interconnects commonly found on IoT devices. It will also walk through communicating with two sensors on a single I2C bus.
