| Remap Makey Makey Mouse Controls |
|
For this project, if you want to use 18 inputs, you will remap the mouse controls on the back of Makey Makey to numbers 1-6. When you attach the Makey Max Backpack after remapping, the mouse controls will now be numbers 1-6.
Download your own Remap Worksheet Make sure you have a Makey Makey of 1.4 or higher to use with the Makey Makey Backpack. (You can remap 1.2 or higher and use jumper wires if you do not have the Makey Makey Backpack bundle)
Follow the illustration on the remap page to place alligator clips. One clip from the up arrow to down arrow and one clip connected from the left arrow to the right arrow. This will put Makey Makey into a remap state.
Once you are in the remap software, hold EARTH and move the cursor on the page by pressing the arrow key inputs on Makey Makey. When you get to the mouse header section, press click, then navigate to change the top mouse input to the number 1. Repeat until you've changed all of the mouse inputs to the numbers 1-6.
 Make sure to save your settings!After all keys are remapped, click the down arrow and tap SAVE to maintain the remapped keys. Until you put Makey Makey into a remap state again, these inputs are now remapped to your new choices. You might want to label your Makey Makey so you remember that it is remapped! Once your Makey Makey mouse controls are remapped, you are ready to attach the Makey Max backpack. Align all pins on the backpack board with the headers on Makey Makey. Gently squeeze the boards together with even pressure, making sure all pins enter the corresponding holes.  Test your inputs on Makey Max with the piano app, or open a document and see if pressing these inputs outputs the numbers 1-6.

| Create Interactive Piano and Scale |
|
To make a physically interactive sheet music, download this printable piano and musical scale.
 Then grab the brass fasteners and conductive tape from your Craft + Code Kit and let's make this paper interactive! Place brass fasteners through each musical note on the scale.  Then fold brass fasteners down on the back side of the paper and place conductive tape from the fastener to the top edge of the paper.
Add sharps to the physical piano, by drawing them in! Use your Makey Makey optimized pencil to fill in the black keys. Make sure to draw to the edge of the paper for the alligator clip to connect.  Place a fastener through for each piano key. You can do this before the tape and make sure the tape touches the brass fastener for each note on the scale and the piano.  Or you can use an exacto knife on the front of the paper to cut a small slit through the paper and tape. Then push a brass fastener though the piano note and through the tape. On the back side of the paper, fold down the brass fastener legs onto the tape to ensure a connection!
 Test your inputs by placing an alligator clip in EARTH and testing each mouse movement to see if they are correctly remapped to the numbers 1-6.
 Test Keys and ScaleClip all of the arrow key inputs on the front of Makey Makey and then clip WASDFG and numbers 1-6 on Makey Makey Max according to how you've set up your piano on the piano app.
 Alligator clip to the max!Now you are ready to test out your full scale piano! What musical masterpieces will you invent?
