Now you know how to make your Arduino talk serially to others, and use this commodity to help you correctly calibrate your sensors or let your projects receive data or even commands from your computer or other serial devices.

From the point of view of hardware, we have seen that almost every physical variable can be easily sensed into Arduino by using variable resistors in a voltage divider configuration.

We have also met the friendly servomotors and we have seen how easy it can be to incorporate one of these helpful motors in our projects.

And finally when talking about programming, we have seen what a library is and how much it can ease the work with different types of devices by providing ready-made functions, objects, and their methods ...
