Chapter 10. Arduino in a Real Case – Greenhouse Control

At this point in the book, we have already seen every important aspect of the Arduino platform, from its inputs and outputs to the use of interrupts and communications.

For this final chapter, I would like to propose a complete project that uses as many concepts as possible that have been seen until now, and I thought that a greenhouse controller could be a good example.

We will even meet a final component, the relay, which will help us deal with external devices not directly connected to our circuitry.

So, let's go into our final project and see how much Arduino can do by simply connecting a bunch of electronic components and writing a little sketch.
