This is another video sponsored by the good people at XOD.
Today I’m working with XOD, a graphical IDE that lets you program an Arduino without writing any code. If you’re new to XOD I suggest that you take a look at my previous XOD video, as well as the article at https://dbot.ws/xod01 and of course the XOD website at https://xod.io 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 As always you can get additional information as well as the code (.xodball files) used in this video by visiting the article at https://dbot.ws/xod02. I hope you enjoy this video and will continue to follow along while I add features to our XOD Robot Car!

I am trying to copy your code shown on this video. When it comes to the part where you connect the INPUT NUMBER node to the "h-bridge" for the Robot.
First. I cannot locate the exact h-bridge you used.
Second. Any h-bridge I select from libraries I have found will not connect to the INPUT NUMBER nodes. Dir, Dir, PWM.I am stuck at this point in the project.
Can you show me what I can do to get this to work?
Thank You
Doug
