- The board will still need power (probably over USB?). You cannot change the power pin in code or switch it on/off. But if the 5V usb is going straight to the vin pin, then you can use it to power external components.aaa– aaa2018-04-16 05:54:50 +00:00Commented Apr 16, 2018 at 5:54

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. arduino-uno), 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
