Summary
In this chapter, we learned how to properly configure and set up the MPLAB X and the Arduino IDEs for the C microcontroller board programming. We were introduced to the C programming language, and in particular, a set of C language instructions necessary for programming the Blue Pill and microcontroller boards. To practice what you have learned about the C language, we looked at a number of practical circuits using the boards' internal and external LEDs. The instructions and structure learned in this chapter can be applied to the rest of this book.
Chapter 3, Turning an LED On and Off Using a Push Button, will focus on how to connect a push button with a pull-up resistor to a microcontroller board, as well as how to minimize electrical noise when using the push button. It will also explain how to set up a microcontroller board's input port via software, along with possible applications of push buttons.
