1First delete everything except initializing and printing the value of the pin from a copy of the sketch; especially disconnect the motor driver. Then use something else like a wire connected to Vcc or Ground to source the input, and verify that you are reading the pin you are switching.Chris Stratton– Chris Stratton2017-06-10 17:31:32 +00:00Commented Jun 10, 2017 at 17:31

@Majenko I have not currently got the ground from the arduino going to the ground on the pi, but the signal from the pi is grounded on the pi itself.Wisaacj– Wisaacj2017-06-11 07:36:57 +00:00Commented Jun 11, 2017 at 7:36

- 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
