![]() ![]() Always remember to connect all components to the ground. The ground is very useful for making a common reference between all components in your circuit. If you have any doubt, double, triple check, and ask someone for help before you burn your board.īut if you follow some basic rules and common sense, you’ll have nothing to worry about!. So, be really careful when you plug something or when you create a test circuit. If you connect a ground (GND) pin to a 3.3V pin directly, well… You might destroy your Raspberry Pi board the second those pins are connected together. There are no real hardware safety when it comes to the Raspberry Pi hardware pins. A word of cautionīefore you plug anything to a Raspberry Pi 4 pin, you have to know that you can easily damage the board if you do something wrong. Now, let’s break down each pin or group of pins, and see what they can do. Here’s a complete overview with all the GPIOs and their primary function. ![]() The difference between Raspberry Pi 4 pins and Arduino pins.Communication protocols through Raspberry Pi 4 pins. #MASTER THE BOARDS STEP 3 USED HOW TO#You are learning how to use Raspberry Pi to build your own projects?Ĭheck out Raspberry Pi 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: If you’re interested about Arduino pins, check out this tutorial: Arduino Uno Pinout Guide. At the end I’ll give you more details about the differences between Arduino and Raspberry Pi pins. You’ll find out that the pins can be quite similar for some functionalities. In this complete Raspberry Pi 4 pins guide I’ll break down all the pins of the GPIO header, and you’ll learn what you can/can’t do with them.Īlong the way I’ll make some comparisons with the pins of the Arduino boards. ![]() It brings the Raspberry Pi 4 much closer to hardware applications, making it perfect for being embedded in a hardware application or product: a robot, a retro-gaming application, etc. GPIOs allow you to easily use hardware features and communication, directly from a computer – the Raspberry Pi microprocessor. This GPIO header is also the same for Raspberry Pi 3 boards, so this guide applies to both versions. As such, I require all students doing individual tutoring with me to also be in group tutoring.The Raspberry Pi 4 board has a GPIO header with 40 pins. Or giving you individualized feedback on your question interpretation so you can do questions faster and get more right.īecause of the huge time-saving benefits of group tutoring, not only do you save money and have each individual tutoring hour be more effective in helping you, but I am also able to serve more students. ![]() Things like tailoring a plan to your specific situation so you can waste less time on tedium and spend more time on the things that matter. And because I’m not wasting time by giving the same biochemistry/cardiology/ventilator lectures to 50 people, each hour of one-on-one tutoring time can then maximally help you improve your exams. Because of the many pre-recorded modules, you can watch them when you want to watch them – you don’t have to wait to go over it with your tutor. Group tutoring turns what would have been at least 50 hours of individual tutoring into a guide to the most efficient way to improve your score. people with high USMLE scores who may or may not be committed educators) and “trained” them in my methods, but the experience for you the student can be too hit-or-miss. I could have hired a legion of “tutors” (i.e. Frankly, for many years I’ve had way more tutoring requests than I could accommodate just by myself. Most tutoring services have a perverse incentive to try and sell you more tutoring hours, because the more they tutor, the more money they make. ![]()
