In this chapter, we have set up our Raspberry Pi to Arduino shield.
The software library for interacting with the Arduino shield is installed and ready for further projects. You have also been introduced to the Arduino programming language and C++ and learned how to compile code.
Following from this, you have written an application that turns an LED on and off.
Now that we have the basics of controlling components attached to our Raspberry Pi to Arduino shield, we can move onto our first home automation project – building a thermometer.
