| Every microcontroller has many pins that can be used to connect external electronic elements. In the examples shown in previous chapters, LED was used. Such LED can be connected to a chosen General Purpose Input Output (GPIO) pin and can be controlled by setting a HIGH or LOW state. Below are some details of the functions that allow the manipulation of GPIOs using the Arduino framework. In the next chapter, analogue signals will be considered. | Every microcontroller has many pins that can be used to connect external electronic elements.
