Elevator Challenge

‘Real World’ vs. Simulation

I challenged my boys to think about how a collection of disparate components come together to form a “complex system” which achieves a useful function. In order to simplify the discussion and to keep the focus on the central aspects, we used an ‘elevator’ metaphor as our example. Our first challenge was to use the Scratch programming language to create the elevator virtually, in an idealized simulated environment. Then I challenged them to do it again using real parts in the real world to see whether the experience would be the same or different…

I have more to write on this subject, but here is a teaser (our build log) from the project.

Cyber-Lock Challenge

I challenged Mason with the task of building a “cyber lock” using an Arduino, Keypad and a Servo Motor to represent the lock. First we mocked it up on Circuits.io (now part of Tinkercad) and then we constructed the actual circuit using similar parts. The complete “specifications” we came up with for the project along with the accompanying code are available below. Continue reading “Cyber-Lock Challenge”
