Summary

In this chapter, we got our first introduction to the hardware and software that will be the heart of our alarm system.

We also learned how to stimulate the hardware using simple switches and an LED. We understood how comparators work and how to use them through this project. We briefly touched on EOL resistors and their significant use in this design.

In the next chapter, we will build the solid hardware that will be eventually connected to the BeagleBone.
