As you know, MIT App Inventor is a graphical-based programming system, or a “visual development” system where programs are constructed by dragging and dropping “blocks” onto a Blocks editor.
Arduino, which we mentioned in conjunction with our Bluetooth interface code, is a microcontroller system that is normally programmed in a language similar to the C++ programming language – which is text-based.
Mitov Softwware has introduced a new visual programming system for Arduino. I have not yet had a chance to try this out – the software is in “Beta” test phase and is not yet generally available.
The simplicity of an App Inventor type programming environment might then be available for Arduino applications. This is very exciting. It may be helpful for enabling more kinds of people, with different types of backgrounds than software developers(!) to write code for Arduino boards.

I have used this screen shot from their web site to illustrate the general idea – really looking forward to trying this out!

As they point out, the cyclical ups and downs in usage suggest App Inventor is primarily used by students – with drop off in usage during school vacation periods.
That suggests an opportunity to expand usage of MIT App Inventor – by insuring that AI2 appeals to a wide audience of potential app developers and not just educational programs!

MIT App Inventor makes many things easier – but eventually one must learn to think like a software developer and become familiar with concepts like data structures, algorithms, design patterns, and software engineering design and project management.

Raspberry Pi 2 is a US$ 35 computer board to which you attach a monitor, keyboard, mouse and Ethernet connection. You can use the Pi 2 for web browsing and other functions, but it also comes with Scratch.
Scratch is a programming system that is very similar to MIT App Inventor. You can learn more about Scratch in our previous post on that topic!
But because one of Raspberry Pi’s goals is to advance computer science education, there’s a few pieces of bundled software that can help achieve that goal. This includes a drag-and-drop visual programming language called Scratch (great for beginners to create animations and games), as well as Sonic Pi (for creating electronic music) and more advanced programming languages like Python (also included).

And speaking of STEM, here are some videos from yesterday’s Oregon City FRC FIRST Robotics Pacific Northwest District 2 (Oregon) robotics competition. 35 high school robotic teams took part, with Team #4488 “Shockwave” taking first by total points. I am biased: I am a volunteer engineering mentor with the Shockwave team, from Glencoe High School, Hillsboro, Oregon. Go Shockwave!

FIRST Robotics is not App Inventor, but FIRST is a high visibility showcase of youth STEM programs. Since 2008, I have been a volunteer engineering mentor with high school FIRST Robotics teams. The 2015 FIRST robotics competition season is underway now.
To learn more about FIRST Robotics in your area, or to start a team, visit USFIRST.ORG.
The team where I volunteer (Shockwave Team #4488!!!!!) has implemented several Android apps using MIT App Inventor. One of their apps, a robotic-themed game based on the 2015 competition, is available in the Google Play store as a free download. Other apps are used by the team during competition to collect data on other teams, which is then analyzed in an Excel spreadsheet (written using Visual Basic for Applications code) to develop optimal competitive game strategies.
(Sorry for no new App Inventor code examples this week – had an ear infection for a few days that caused dizziness. Everything is okay now!)
