- As joan points out, the statement "Arduino pins more or less follow the input voltages" is false. Arduino input voltages are variable and the pins regulated. For a 5V model you need to use at least 5V input for correct functioning. Also worth noting that an MC != a SoC, although there are similarities and the latter term is sort of ambiguous/conceptual.goldilocks– goldilocks2016-05-02 15:10:14 +00:00Commented May 2, 2016 at 15:10

- 3"If I am supplying the Pi with 5V, why are the GPIO pins not 5V tolerant?" - For the very same reason the Arduino GPIO is not 12V tolerant even when you power the board with 12V.JimmyB– JimmyB2016-05-02 18:27:35 +00:00Commented May 2, 2016 at 18:27

- 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
