In this chapter, we have built three projects using Arduino. This is just a start and the projects are simple. But if you build them and add more components to your Arduino, who knows, you will build something really awesome. My suggestion is, just come up with an idea of what you can do with your Arduino, collect the components from a store, and then build it. For example, you can add a number of components to the Smart Weather Station project, such as soil humidity sensor, GSM module, Bluetooth module, Wi-Fi module, warning bells, and so on. Just think of what can be done to make a project more useful. In the last eight chapters, you were trained to do anything with your Arduino. From blinking an LED to building a super computer, all can be done with Arduino. All you need is to do what comes to your mind, and then see the output. If you find problems with code or hardware connection, ask the Arduino forums and search online. I hope no one would be able to make a better project...
