Foot switch

Any tips for using the microswitch on the foot? I've found that the switch causes Marty to turn rather than activating. I guess a longer leaver should sort that? Perhaps could print something.

Also when coding in Scratch how can I record a switch activation whilst in the middle of a walk?

Cheers Sandy, we'll give that a go and experiment with toecaps

Hi there!

Yeah, you could use microswitches with longer arms to detect bumps over a larger area. Or we could maybe make some 3D printable bumpers to cover the switches and extend the bump area - if there was a demand? If you do make something please do share it with us!

For sensing while Marty moves in Scratch, that's quite fun actually. There are a couple of different ways you could do it, but one way is to have a separate thread running to monitor the switch, while the movement happens

That would look a bit like this:

You could experiment with stopping and pausing, or different movements in general. You could also look at turning off blocking mode and trying to react more quickly to a bump.
