IoT devices involve a combination of software and hardware. This module provides background on the basics of hardware design and wiring needed to build useful circuits. This module describes the functions of basic passive components and describes how to use them in simple circuits. This module also describes how to wire circuits together using a breadboard. The goal of this module is to enable students to design and implement the circuits they need to interact with basic sensors and actuators.

This module introduces sensors and actuators and discusses how to interface with them. We’ll examine different classes of sensors and actuators. For each type of sensor/actuator, we’ll examine the circuitry needed to interface with it. Additionally, we’ll take a look at the Arduino code needed to communicate with the sensors and actuators.

This module introduces the use of software libraries with an Arduino sketch. One of the best aspects of the Arduino environment is that the use of good libraries allows a programmer to use complicated hardware without dealing with the complexity. The Arduino environment is supported by many libraries and this module examines the use of several of the more common libraries that allow the use of hardware peripherals in the microprocessor.
