Les broches du GPIO peuvent être utilisées comme sortie ou entrée digitale. As digital outputs, you can write programs that turn a particular pin HIGH or LOW. Setting it HIGH sets it to 3.3V setting it LOW sets it to 0V. To drive an LED from one of these pins, you need a 1kΩ resistor in series with the LED as the GPIO pins can only manage a small amount of power.

The GPIO pins can be used as both digital outputs and digital inputes. As digital outputs, you can write programs that turn a particular pin HIGH or LOW. Setting it HIGH sets it to 3.3V setting it LOW sets it to 0V.

If you use a pin as a digital input, then you can connect switches and simple sensors to a pin and then be able to check whether it is
