Description: You may be the greatest living banana-pianist, but how will you ever know if you don’t make yourself a banana piano? Good news, that project and countless others are easier than you think they are with MaKey MaKey.

Using the MaKey MaKey you can make anything into a key (get it?) just by connecting a few alligator clips. The MaKey MaKey is an invention kit that tricks your computer into thinking that almost anything is a keyboard. This allows you to hook up all kinds of fun things as an input. For example, play Mario with a Play-Doh keyboard, or piano with fruit!

The MaKey MaKey uses high resistance switching to detect when you’ve made a connection even through materials that aren’t very conductive (like leaves, pasta or people). This technique attracts noise on the input, so a moving window averager is used to lowpass the noise. The on-board ATMega32u4 communicates with your computer using the Human Interface Device (HID) protocol which means that it can act like a keyboard or mouse.

There are six inputs on the front of the board, which can be attached to via alligator clipping, soldering to the pads, or any other method you can think of. There are another 12 inputs on the back, 6 for keyboard keys, and 6 for mouse motion, which you can access with jumpers via the female headers. If you wish to use a different set of keys, or otherwise change the behavior of your MaKey MaKey, you can simply reprogram it using the Arduino environment. Oh yeah, we didn’t mention that the MaKey MaKey is an Arduino-compatible controller? That’s right, it runs the Leonardo bootloader so reprogramming is fast and easy.

The Deluxe Kit includes everything that the basic kit does plus another pack of alligator clips, a pack of jumper wires and a roll of copper tape so you can really go crazy!

Note: We’ve updated the firmware on the MaKey MaKey along with our other ATMega32U4-based boards. Check out the Firmware Note document below.

  • Looking at the revised v1.2 JoyLabz Makey Makey board, it looks like they are using a PIC chip instead of an Atmega32U4 with an Arduino bootloader. The PIC chip is a different microcontroller so you are not able to upload the Arduino code to remap the keys. There is a different method to remap the keys with the revised JoyLabz Makey Makey board. You should look at this link to see if you can remap your board with the PIC chip =>

  • I was wondering if it is possible to after adding the Bluetooth and LiPo ad-on, can you strictly use the makey makey wirelessly? I would like to make an enclosure. my practical use would be as a joystic

My son loves it!!!

I bought the Makey Makey for my son for Christmas. He loves it. He wanted to be an engineer one day. Well worth the money.
