Earthquake machine with Lego and Microbit
The idea for today's project came from making a competition in my class to see who could design a building that can survive an earthquake. I saw this same idea in Lego Masters and it looked fun. Unfortunately, we didn't get to do it because we ran out of time before the school year finished, but I learnt a lot in the process. This project is about an earthquake machine that I built with Lego and Micro:bit. It features 4 different speeds to make increasingly harder to survive and also resembles a bit what would happen in a real earthquake as the P, S and surface waves arrive. Here is what the full thing looks like so let's delve into more detail. As you can see here, when you pay close attention we have reused the Minecraft salvation console because it also used a 9 volt pump so all I had to do was switch it out for my 9 volt Lego motor and it was good to go. In this image below you can see the motor shield that I used to drive the 9 volt motor for this project. It is the ...
