Tomorrow, Friday January 11, 2013, Inventory Day. That means pretty much every SparkFun employee will be busy counting all the things. Thusly, orders won’t be going out tomorrow. Our apologies for the inconvenience! Now on to today's post...
If you've ever taken a class at SparkFun, there's a pretty good chance you've met Jeff Branson, Educational Outreach Coordinator in SparkFun's Department of Education(DoE). Jeff, along with the rest of the DoE, has been hard at work to further SparkFun's educational efforts.
Part of his efforts has been creating videos on fundamental concepts of DIY electronics. Today we would like to share a two-part video series on the basic in's and out's of robotic motors. Keep in mind these are designed for the beginner, but you might be surprised at what you can learn! Check them out:

The H-bridge tutorial can be found here
If you have any questions, please leave them in the comments below. We would also love to hear your ideas for videos of this kind in the future - what would you like to learn more about? Thanks for watching!
Jeff, you got some real talent at lecturing! You do a great job at getting your message across, keep up the awesome work.
For the first video could you put up schematics for the transistor and diode circuit thanks
Excellent video, Jeff! I recently decided to build the 'ultimate cat toy' and started with the Magician Chassis kit. I'm quickly finding that I need something super light and super fast but with enough torque to carry a few IR seasons...
So how do you decide on a motor to use? I assume higher voltage means faster and higher current load means higher torque?
Also - specs on the H-Bridge say 36v is the max. So in this case, could you run a 9v batter or something to the motor supply of the H-Bridge (and drive a 9v or more motor with the Ardiuno)?
I loved watching the tutorials, but since I am deaf, I missed all the voice instruction. I wonder if there is a text-based web page presenting each tutorial? I expect I can probably find text introductions on other websites as well; I'll Google. I assume your tutorials focus on the latest techniques and parts.
I agree. YouTube does have the (CC)to give you English text, but the person speaking really has to be aware to speak clearly. Plus, YouTube really sucks at all the tech speak
Bob, I'm glad the tutorial helps, please use the link under the second video for the text version. Jeff
Great video Jeff, I like the simplicity that gradually keeps adding on to it self towards the end of the video.
Err you got "Turn Right" twice on the whiteboard in the second video. Maybe you need a voice-over to correct it.
