Don't have a banana? Try experimenting with different materials. Some materials conduct better than others.
Certain materials can also be conductive over a period of time. Try it out!
Below is an example of a hand-drawn key from a standard pencil. A dotted circle was drawn on two sides of a
piece of paper and extended to the center. Lines of alternating lengths were drawn (short and long) from each
extension with a gap between the lines so that one finger could be used as the key.
The first drawing with the thin lines labeled "Button 1" was a poor conductor on paper. However, the second
drawing with the bold, thick lines labeled "Button 2" was able to conduct. In this case, the pencil was only able to
conduct when there was enough of the material. After a few uses, the lines faded and required another layer of
graphite.
Using the Back
Remember the black connectors on the other side of the board? There are additional keys that you can connect!
You can follow a similar set of steps, replacing alligator cables with jumper wires. The wires included with the
Makey Makey is one type of jumper wire. Jumper wires can be a bit tougher to connect to keys. An easy solution is
