GPIO Pinout for Raspberry Pi 4 and Earlier.(Image credit: Les Pounder) General Purpose Input Output (GPIO) Pins The GPIO is the most basic, yet accessible aspect of the Raspberry Pi. GPIO pins are digital which means they can have two states, off or on. They can have a direction to ...
In this tutorial, we are going to take a look at the basics of the Raspberry Pi’s GPIO pins, also known as the general-purpose input and output pins. These pins are essential for communicating with other circuitry, such as extension boards, custom circuits, and much more. LATEST VIDEOS ...
GPIO Pins These are the pins on your Raspberry Pi that perform various functions and each pin is assigned a different task. Some pins are used as inputs, while others are used as outputs. Input voltages ranging from 1.8V to 3V are considered high voltage, while voltages less than 1.8V ar...
In addition to controlling external devices, the Raspberry Pi's GPIO pins can also be used for reading input from sensors. This allows users to create projects that can respond to their environment, such as temperature sensors that adjust a heating system or motion sensors that trigger an alarm...
