1Instead of an input for each key you can use a matrix and use the 18 inputs to handle 81 keys (a 9x9 matrix) as far as I know the RPi has fewer inputs than the arduino so I don't think it will help.Craig– Craig2012-09-25 19:35:47 +00:00Commented Sep 25, 2012 at 19:35

@Craig so you mean combining inputs like this: arduino.cc/playground/Main/KeypadTutorialsventechie– sventechie2012-09-25 19:58:39 +00:00Commented Sep 25, 2012 at 19:58

@sventech yes. I'm not familiar with the makey makey so I don't know how its high resistance switching will interact with the matrix.Craig– Craig2012-09-25 20:30:25 +00:00Commented Sep 25, 2012 at 20:30

How to Edit
- Correct minor typos or mistakes
- Clarify meaning without changing it
- Add related resources or links
- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
-
create code fences with backticks ` or tildes ~
```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible)
<https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. pi-3), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
