Showing off your stats with the serial monitor
In this chapter, I discuss some of the basic sketches needed to get you on your Arduino feet. This chapter covers a broad range of inputs and outputs using the sensors in your kit. If you don’t yet have a kit, I suggest reading through Chapter 2 to find one of the recommended ones.
The Blink sketch (described in Chapter 3) gives you the basis of an Arduino sketch. This chapter expands it by adding circuits to your Arduino. I walk you through building circuits using a breadboard, as mentioned in Chapter 4, and introduce a few new components from your kit.
I detail uploading the appropriate code to your Arduino, walk you through each sketch line by line, and suggest tweaking the code yourself to gain a better understanding of it.
