Arduino Log #2: Trial and Error (Mostly Error)

Setting up the Arduino R3 is a learning experience in itself

Earlier today the Arduino Uno Rev3 arrived, and I was excited to get it up and running, bearing in mind I wanted to do this without virtually any research whatsoever to get a true feeling of a newbie. The box was much smaller than I thought, and lacked one thing that I’m surprised wasn’t included in the box considering the price… a USB A to B Cable (typical Printer Cable type).

My Arduino R3, featuring an extremely long Printer cable as one wasn’t provided

Ok… sourced a cable… plug the Uno in… not much happens… the power LED on the UNO lights and an orange LED flashes, Windows doesn’t show anything. Turns out you need to download the application to install the drivers to run.

Ok… all installed… let’s start with the first example on the Tutorial area of the arduino site (because I don’t have any kit except the Uno itself), the Blinking LED. Turns out this has already been included in the program under File -> Examples -> 01.Basics. All i need to do is click “Upload” right?

Wrong…

After some confusing looks, it turns out the screenshot above is deceptive. Although on the bottom right of the screen you see “Arduino/Genuino Uno on COM1”.. this port is actually taken by the PC as a Communications Port. When going to Tools -> Port, you can see that the Arduino is actually hanging around on COM3

After that, the code uploaded successfully. Awesome, I now have a speed adjustable flashing LED.

Now to see if this runs on a Chromebook. From the looks of it there are (or were) two options to get the board running, Codebender and Chromeduino. Arduino themselves currently have a closed beta, which can be signed up to, but there is a few week wait to get “on board” (pun intended)

Great, let’s try Coderunner… browses to the website…

codebender.cc is closing down. Registration is disabled.”

Oh… turns out the guys have been paying out of pocket for this project and the cost has beaten them, with the closing starting back in October 2016. Shame, it looks to have been a very successful project as Chromebooks are known for educational devices.

Ok… Let’s try Chromeduino… installs chromeduino and plugs in Arduino…

Looks like this app needs to upload to an intermediary server before pushing down to the Arduino, and that server doesn’t seem to be accessible. Damn.

Well, we’re halfway there (living on a prayer). I’ve got the board working on a Windows Machine so that will do for now, and I’ve got my on-board blinking LED, and a potential beta invite for a chromebook version at Arduino. For now, I’m satisfied.
