This Instructable is the simple version of the MaKey MaKey Monome, an electronic music instrument designed to be easy for kids and beginners to reproduce (and iterate upon!). For more information, feel free to check out my website.
Materials (for the 4x4 monome)
Get the Arduino code
Get the Processing code
NOTE: Make sure the pin mapping in the Arduino code corresponds to the mapping of the pins to the copper tape (i.e. they're in order from left to right, top to bottom, or vice versa)
NOTE: Unlike in the MaKey MaKey Monome version, you do not need to touch ground in order to trigger a key. Just touch the intersection of a row and a column with you hand.
Once the Arduino code is uploaded to the board and the board is plugged into the computer, you can run the Processing monome.pde sketch and make sound! Check out the other MaKey MaKey Monome tutorials for additional information about the sketch.
