Add a Teacher Note to share how you incorporated it into your lesson.
Cut two pieces of aluminum foil tape a two pieces of cardboard to the same size.
Attached the aluminum foil tape to the pieces of cardboard.
Cut two thin strips of foam.
Put the two strips of foam on one of pieces of cardboard.
You can use glue for this if you'd like, but it's not necessary since we'll be using a rubber band later on.
Put a rubber band around your button.
Attach an alligator clip from EARTH to one of the cardboard pads, and SPACE or CLICK to the other.
How when you push down on the switch the Makey Makey will send a signal to the computer.
Here's a primer on simple switches from our the Tinker Studio.
Step 9: Extensions (Optional)
Now from here there's lots you can do.
You can measure how much weight your pressure pad can withstand before sending a signal like a kind of scale. You can increase the amount of foam or size of your switch to make a heavier scale!
Or you can make a series of these for a musical hallway, or a DDR pad, or a relay race track.
