11/5/2023 0 Comments Arduino wire library set sda pinThe ground is essential for the Arduino board to measure and set any voltage. Ground pins are often represented by GND on schematics. If there is one thing, and only one thing that you should remember with the ground, it’s: always connect all grounds of your circuits together, and make sure all components are correctly linked to the ground. So, let’s break down each kind of pin, one by one. You may find that quite difficult to understand at first. Here’s a global visual description of all the pins you can find on an Arduino Uno board. Communication protocols through Arduino pins. Powering components from the Arduino Uno power pins.You are learning how to use Arduino to build your own projects?Ĭheck out Arduino For Beginners and learn step by step.Īfter watching the video, subscribe to the Robotics Back-End Youtube channel so you don’t miss the next tutorials! > Watch this video as an additional resource to this article: This post is focused on Arduino Uno board, but most of the explanations (except for the pin numbers on the circuit board) are also valid for any other Arduino board. I’ll also give you some examples of sensors/actuators that you can use with each pin functionality.
