Summary
This chapter was particularly interesting and hands-on because we learned how to manipulate hardware from software! This is exactly the reason why the Raspberry Pi and other boards with GPIO pins have become so popular. They allow you to control real-life hardware applications with software.
We can create potentially unlimited applications for the Pi just by changing the sensors connected to it and tweaking the code. We can build stuff such as home automation systems, security applications, wearable devices, and many more with just this small board! In this chapter, we had the humble beginnings of such projects where we first learned to blink an LED, which wasn't very impressive by itself. Then, we learned how to control that same LED with ...
