Arduino Programming with XOD #2 - Robot Car

Build a Robot Car and program it using XOD, a graphical development environment for the Arduino.

This is another video sponsored by the good people at XOD.

In this video, I will be showing you a couple of new techniques with XOD.

First, we will learn how to use multiple patches in our XOD projects. This will allow us to create our own custom nodes, a powerful technique that also makes our main patch a lot less cluttered.

We will also learn how to use XOD libraries. Today we will see how to add a XOD library to our IDE.

In order to make things more fun, I’ve decided that for this video and the XOD videos that will follow we will build a project - a XOD powered robot car!

In this video, I’ll show you how to assemble the robot car. Our initial design will use an L298N H-Bridge motor controller and a 10mm RGB LED. As the series continues we’ll add more parts to give our robot more capabilities.

Here is what is covered in this video:

00:00 - Introduction
03:32 - XOD Robot Project Intro
07:18 - Robot Car Wiring
11:16 - Making custom node for RGB LED
19:12 - Adding a XOD Library for L298N
26:05 - Sequential Programming Intro
27:42 - RGB LED Sequential Node
44:44 - L298N H-Bridge Sequential Node
51:45 - Robot Demo Sequence

I hope you enjoy this video and will continue to follow along while I add features to our XOD Robot Car!

Thank you for sharing your knowledge. I sealed the interest in electronics and computers many years ago. After I discovered your channel, my blood is boiling and my brain is on fire. Now I have reopened my workshop and wiped the dust off the multimeter and power supply. Many tons of Arduino stuff is being delivered by my local postman (lady) these days. I'm back in business.! You are a great teacher and I have become a fifty-five year old student.

Another great teaching video!! I'm just starting to understand the programming of the Arduino, and your lessons have made it start to sink in. Thank you so much, and keep up the good work.

Excellent tutorial, just like all of your other tutorials. I can't believe you do all of this for us to learn for free. How can we help support you so you can continue with these great tutorials. Again thanks.

Your previous (introductory) video about XOD was excellent, but it left me with questions, such as how can I import, or custom make a patch for new hardware. You answered those questions right away in this video, and once again your presentation was clear, concise, and very easy to follow. By the way, I wish my workbench was half as neat, clean and well organized as yours is.

You are an excellent teacher and I've been watching your video's for a couple of years!I can say that I learned a lot from you :-)...  I'm an AMA Pilot that fly (Prop Planes, Quad's and Jets). For the last two years I've been making projects with Arduino thanks to you its been coming along very well,  Thank You!!!

[devharsh]

You are really good teacher. The data (article, resources) are so perfect that we can learn many things from it and recap all. Seriously gonna try it on my robot which is day by day going more complex and I am looking for different way of programming. XOD looks good to me to start.

[opalprestonshirley]

This is gonna be fun. This was a great tutorial for using XOD loads of interesting things as your article says. Looking forward to much more. Thanks for all your hard work.

Another well put together tutorial and video production. Your videos are always well done, as well as this one. Thanks for all of them. I like the way that you started with small steps and now have gone to a much bigger project. I subscribed long ago and I promote your channel every time that I get a chance. Keep up the great tutorials, thank you!

Even tho' I prefer to use the Arduino IDE, XOD is an excellent way to prototype projects. It's also great way for kids and individuals to learn to program the way BASIC got people involved in the early days of personal computing. I've been having a blast just playing with it and I think XOD should be included in STEM courses in schools to get kids involved in system programming. I laud your patience and dedication bringing this art to the public. I'm going to recommend this to our local libraries STEM program for kids in our area. Thanx>>

really great stuff, been playing with arduinos for about 3 months and really enjoying the learning i personally use VSCode for my IDE but always been a fan of node editors and going to check this out for sure. By the way you videos are amazing and your knowledge you pass on to us is very much valued thank you

[emjds]

You are an excellent teacher your explanations are very clear thank you. I am just a simple hobbyist, but I learn a lot from your Arduino projects thank you.

Another great instructional vid. Thanks again. I am starting to get a little bit intimidated by XOD- I guess all programming, no matter what language or format requires some unanticipated mental investment ☺. Nothing comes too easy that is worth doing.

[rosie]

Pretty damn cool . Kinda programming thru flow charting. A lot different from when I did programming years ago! Great video!

[brett-sf]

please more xod! i find it really interesting

[DancesWithRobots]

I just watched the two XOD videos (Having watched them upon their initial posts.) I'd forgotten about them and recently rediscovered XOD while searching for a visual programming language. You planned other videos in the series but never got back to XOD. I understand things happen, but I'm a little disappointed. These were great videos that taught me a lot about XOD over the course of two hours.

[sashabalmagia]

You are really good teacher, your videos are very helpfull please do more XOD videos, thank you!

[opalprestonshirley]

A great presentation, I'm gonna have to get the robot car. Thanks.

[spesinskis]

Tires are directional, but put on not correctly providing different grip. Also, weight distribution - you need to add counterweight.

[tomaims]

Are you planning more "XOD" tutorials? You indicated that you planned more but I have not seen any additional ones either on YouTube or your web site. I hope you will do more in the future.

Love your channel, learning tons, thank you!!
