Education Engineer @ Sparkfun

With over 5 Million units sold in 2014 alone, Chromebooks are a growing trend among schools and homes. One of the biggest drawbacks to Chromebooks has been the inability to connect it to any hardware (i.e. Arduino) -- until now.

Courtesy of Terrence Fagan, Engineering Chair at Central Piedmont Community College. Terrence has done a lot of great work in engineering education and outreach in his community. He had the opportunity to attend the Fab10 Symposium in Barcelona last July. When he started telling me about his experience there, I felt it was a must for a blog post.

Last Friday at Skyline High School, rather than taking a traditional final exam, students in the Introduction to Electronics class with Ms. Vadovzski prepared poster presentations of projects that they created during the semester. Each project was required to demonstrate some type of interactivity using an Arduino and traditional electronics.

We often teach beginning learners that the standard 16 MHz Arduino Uno is fast... really fast. 16 MHz means 16 Million cycles per second -- or that translates to 1/16 millionths of a second per cycle. That's a mere 62.5 ns. That's fast. So, is the Arduino _really_ that fast? Let's see...

On the third Thursday of every month, the Denver Museum of Nature and Science hosts an evening event for adults in the area called, Science Lounge. Their programming features live entertainment, demonstrations, hands-on demos, and an evening filled with science, education, and exploration! Each month features a different theme. For April, the Science Lounge theme was “Electrify!” What a perfect match for us here at SparkFun!

A simple search on-line for "Arduino resources" results in "About 3,920,000 results (0.30 seconds)," but if you're just starting out and interested in getting Arduino into your classroom - this can be terribly overwhelming. So - here's a list of some of the sites I like to use.

Learn the difference between 3.3 V and 5 V devices.
  • We currently do not have any plans to design / build a Mega version of this shield, but if there is enough interest, we can bring this up in our next new product proposal discussions. Please let us know if this is something you think would benefit you as well as other builders / makers / hackers out there!

  • Here are the correct pins – at least the ones that I think are relevant:

    TB6612FNG Dual H-Bridge DC Motor Driver

    • L_CTRL_1 – pin 2
    • L_CTRL_2 – pin 4
    • PWM_L – pin 5
    • R_CTRL_1 – pin 7
    • R_CTRL_2 – pin 8
    • PWM_R – pin 6

    XBee Port with HW/SW Serial Switch

    • SW_Serial TX – pin A0
    • SW_Serial RX – pin A1
  • The 4 AA batteries are rated at 1500 mAh. In series, this is still 1500 mAh of “energy” to the robot. Your 10,000 mAh power pack will run for considerably longer.

  • Yes. Thanks! Crouton and ChrUbuntu are both alternative solutions to this – but, if you’re in a school, it’s unlikely that you’re going to dual boot or have students boot into an alternative OS for you classroom projects. I ran the Arduino IDE under ChrUbuntu a while back, and it worked like a charm – installing ChrUbuntu and trying to get teachers / students to do the same seemed like too much. But – yes, there are other solutions to getting a ChromeBook to run Arduino. Booting it into a more fully featured distro of Linux is one of those ways.

  • Thanks @swarren. Fixed the link.

  • Has anyone tried using Upverter? It appears to work on my chromebook! Maybe that’s the solution for teaching some PCB design in the classroom too?

  • @jkurleto – Thank you for the feedback. Yes. Chromeduino also works, and it’s been around for a while, but it was a little buggy when we tested it – especially for use in a widespread classroom setting. It uses AVRChick (ChromeOS version of AVRdude) – which is pretty slick.

    And, if you want to give it a try – there is a beta release of a blockly version of codebender http://blockly.codebender.cc/ – it’s still missing some real key features like clone/duplicate, but it’s a great demonstration of the two working together.

  • The original version of the library has a feature that causes the RedBot to stop when it is bumped. This was creating some issues, so this feature was removed, and now the only thing you can do is read the state of the bumper. We apologize for the change in the revision.

  • Glad to hear the PicoBoard example worked! It’s a great additional feature to the DS. To answer your question, the DigitalSandbox can be re-programmed with any standard Arduino Sketch. The original condition generally has something like the Blink example loaded on there. You can find this under File –> Examples –> Basics –> Blink.

    If you’d like to see some examples of code that you can try out on your Digital Sandbox, check-out our virtual Digital Sandbox here.

  • That’s very cool. Thanks for sharing that. I love what the team at RevRobotics have done. The RIOduino is pretty cool. We are definitely not looking to copy or re-invent something that’s already been made. I also really like their new structural system!
