The STEMnet programme here in the UK enables people who are interested in sharing their expertise in STEM subjects with the next generation are given some support to do so. Schools ask their local STEMnet coordinator for help and volunteers step up and go along.
Yesterday at the Intech science centre (our local hub for STEMnet) I helped run an ambassadors intro into Arduino (and also a little bit of Scratch too).
Intech had bought 8 arduino starter kits. These are fantastic combinations of components and projects that have now become more official within the arduino community.
The packaging and collection of it is very professional and whilst still all based on open source it provide way more than I was expecting in the pack. Before seeing the kit I has thought we could start with the basics of the blinking light (a standard piece of code) using the onboard LED, then build the flashing light, then cut and paste and build 2. Basically following the 3 minute piece we did on Cool Stuff Collective
The basic presentation I used was this one, it was not designed to be overly pretty as it was just a catalyst to get things going.
I also did not know what the experience of each of the attendees was likely to be. As it was we had a great and helpful mix of people who knew lots, and were very advanced hardware engineers, some traditional IT professionals and programmers and some very enthusiastic newcomers to the subject (but technically literate)

The aim of the pitch was to suggest the basics (inspired by the basics in Choi Kwang Do)
I thought most kids would want to be into programming initially because of games. There is an instant disconnect between seeing all the code and the effort for a AAA title that can be quite off putting.
So I settled on the light switch as a real world blended reality example. Layering on that the Arduino is a swicth we can control, but that the basics of input, process, output or sense, decide, respond are the fundamentals of everything. So if you get a basic piece of the experience dealing with getting some user input, deciding what to do and then making a change with an output you cover an awful lot of ground very quickly.
Very often as techies and engineers we all see the intricate detail, we become very aware of everything that we don’t know, how complex details can be. However if we treat the knowledge as a set of repeating patterns, like a fractal image we can talk about a basic building block without worrying about the complexity of the overall picture. After all you have to start somewhere.
Anyway, a huge thankyou to Sarah at Intech for hosting and for getting all the kit and for asking me to help in the first place 🙂 A huge thankyou to the group of Ambassadors that braved the potential snowstorm and dived and all had a go and got everything working in the few hours we had. It helped to debug what we need to tell students and other ambassadors.
