 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.

 Microcontrollers' digital inputs and outputs allow for connecting different sensors and actuators to the board. Digital signals can take two values – //HIGH//(1) or //LOW//(0). These states correspond to high voltage (usually corresponding to the power supply voltage of the microcontroller) and low voltage (around 0V). These inputs and outputs are used in applications when the signal can have only two states. Microcontrollers' digital inputs and outputs allow for connecting different sensors and actuators to the board.
