is it a Wenos D1 mini or a NodeMcu? don't mix numbers and D labels for pins in one sketch. arduino.stackexchange.com/questions/75704/…Juraj– Juraj ♦2022-08-02 16:59:55 +00:00Commented Aug 2, 2022 at 16:59

io 5 is D1. it is a good choice for the CS pin, but then you have to wire the SD card's CS pin there, not elsewhere. but D1 and D2 are default pins for I2C (Wire) so I guess you have a sensor wired to D1/D2.Juraj– Juraj ♦2022-08-02 17:06:54 +00:00Commented Aug 2, 2022 at 17:06

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. 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
