MakeyMakey is a circuit board that can connect to everyday things (that are conducive) and turn them into keys on your computer!
Carefully plug the mini-USB cord into the MakeyMakey circuit board.
Let's set up the MakeyMakey board to play an online version of Tetris, with playdough!
Clip each of your alligator clips onto an arrow as shown here.
Grab your piece of cardboard and trace one of your hands on the piece of cardboard with a permanent marker.
Taking a long piece of aluminum foil or foil tape, fold it into a long strip, and wrap it over the hand mark and around the cardboard. Tape it on the back to keep it in place.
Taking another alligator clip, clip one end of it onto the aluminum foil on the cardboard hand cutout. Clip the other end to the MakeyMakey circuit board at the bottom. This will "ground" the circuit.
Take the playdough and flatten them into pancake-like shapes. Each color will represent a colored direction arrow, so arrange them like you would on a computer keyboard.
Push the other ends of the alligator clips into each of the playdough clumps. Make sure to line up the up, down, left and right to the correct arrow positions!
Your final setup before plugging the USB into the computer should look like this.
Plug the USB cord into the computer
On the laptop, click on your browser icon in the taskbar to open the browser.
We made a "MakeyMakey" folder which has all of the links for the games. Find "Tetris" and click on it. Here's the link: www.freetetris.org/game.php
This is how it should look after clicking on Tetris.
When the game launches you can use the arrow keys on yor computer or... use the playdough arrows to play the game!
When you're playing Tetris, make sure one hand is on the foil to ground the circuit. Use the other hand to play Tetris with the playdough arrows!
Let's set up MakeyMakey as a piano!
We'll use the back of the MakeyMakey so we can have more "keys" to program. We made a bundle of alligator clips soldered to pins to fit the board. These wires will let us have more banana piano keys.
Here's a close up of the end that goes into the MakeyMakey board. We just snipped off one end of each alligator clip and soldered those wires to the "header" pins. You can find headers online.
Plug it in on the back of the MakeyMakey board on the left-hand side. Set up the rest of the alligator clips on the MakeyMakey circuit board as shown.
Clip the other end of the alligator clip to the end of each banana. Make sure it is clipped securely! The bananas will become the piano keys.
Plug the USB into the computer to connect MakeyMakey
Open the Google Chrome browser again from the taskbar.
To set up MakeyMakey as a piano, we are using a terrific online virtual piano called "Eric's MK-1" You can find the link here: goo.gl/nN3SdZ
This will launch the MK-1 keyboard that is compatible with the MakeyMakey board. Use the bananas as piano keys to play your own masterpiece! Try different keys and samples to change the sound.
Remember to place one hand on the "ground" (the hand outline on cardboard and foil tape) and tape each of the bananas. Now you're ready to compose your next piano masterpiece with fruit!
