You can read the full explanation on Justin Eng’s blog. You may ask why I 2C? Well, long story short, this is the only way supported by NXT/EV3 other than Bluetooth, which has many disadvantages if used. It’s a great idea to be done, and my guide includes something of that. Although it’s beyond this tutorial, with clever coding and polling, the Arduino can be setup to control the NXT/EV3. The NXT/EV3 must always be a master and can never be a slave. In this tutorial, we setup the Arduino as an I2C slave, and the NXT/EV3 as an I2C master. The NXT/EV3 and the Arduino can be made to talk over I2C. If you’re not that geek, you can skip this section, but I suggest you read at least the last paragraph after the diagram. This section is for the geeks who like to understand everything happening between NXT/EV3 and the Arduino Uno. A special section in this guide will talk about that. After trying to use the Arduino Mega 2560, I can say that they’re not totally right. One more thing to say, The Dexter Industries guide uses Arduino Uno, but they say that it can be done using almost any Arduino board. This guide summarizes all the information from those guides, and includes my special adding that makes the Arduino Uno works with the NXT/EV3 as if they are one entity.
Anything quoted from his guide will be noted between …. The third guide was written by Justin Eng, a college student who relied on Dexter Industries’ guide to make a project and shared his work on a blog. Anything quoted from these guides will be noted between …. These guides are made by Dexter Industries and they are a very good start, but you will feel like you still need more to complete your project. The first and the second guides are maybe the first guides ever written on the internet about connecting the NXT or the EV3 with the Arduino Uno. To be honest, this guide is developed from other simpler guides. Of course it depends on how fast you get bored, and how much time you spend on this in a day. I would say about 2-3 days of reading, understanding and testing before you can apply it to your own project.
#Robotc arduino update#
I will update this article in the future to add the LabView programming.īefore you go further, you must know that this is not a “Master the I2C between NXT/EV3 and Arduino in 5 minutes Guide”. In this guide, I will give you a step-by-step guide to master this, whether you are using NXT or EV3, whether you are using LEGO Mindstorms graphical programming or RobotC. Well, this is the answer to your prayers. I have worked on NXT and EV3 using the LEGO Mindstorms graphical programming and RobotC for some years, but you always feel like you need more motors and sensors without using another brick, or you want to extend the functionality of your project. This is my ULTIMATE guide for connecting The NXT or EV3 with the Arduino Uno.
