Hi everyone.

A bus that does engineering STEM activities has a lot of mechnical/manufacturing goodies to show the kids but they don't currently have anything electronic.

I need an idea for a little mini project. Just a PCB that I show kids that would be interesting to look at.

Does anyone have any project ideas I could have a go at?

It needs to be a low budget project as it will have little or no funding.

Many thanks in advance for any suggestions.
