We’ve all created volcanos in DT, but how about simulating one using physical computing? This was the brilliant idea of a teacher up in Doncaster who then requested some support in how to achieve it.

There are numerous possible solutions, but this is the way I would do it. I’ve not tested the real thing, so I’ve no idea if the motors would be powerful enough to push the syringe, or if the liquid would ‘erupt’ or just dribble! Or how much the LED’s would be visible… BUT this is how I would do it!

This is my proposed diagram, or ‘design algorithm’:

And here is my explanation!

Here is my wiring solution:

Here is the code diagram:

Here is the link to a GDrive folder, with all videos, pictures and also the actual save Crumble code.

Let me know if you’re going to give this a try, and if it works!

Happy volcanoing!!
