So during my sensor research I found a motion detector sensor I thought was interesting:
And this tiny servo which I loved because of how tiny it was:
I've always thought touch sensors were interesting, like in touch lamps:
And this water sensor is cool too:
If this is what I think it is I think this would be cool to mess with, a tilt switch:
This orientation, motion, and gesture sensor is interesting as well:
Ok I feel like this is too many to pick from, they're all super cool, I can't decide!
