Chapter 4. Burglar Alarm – Part 1

In the previous chapter, there were a lot of coding skills to take on board. Understandably, it was difficult, but you made it through. In this chapter, we will use a lot of hardware and software. Haven't you always wanted to make your own burglar alarm? Catch the crook who stole your favorite cookies from the cookie jar? This chapter will teach you how to do just that.

• The PIR sensor
• Testing the camera
• Communicating...
