 ### Notes and Limitations:
  - This currently **only supports NVIDIA GPUs**
  - This currently **only supports normal PWM**, not delta PWM
- - **You will need to set the port of your arduino manually** (in the Python code as the `port` variable)
-   - There are instructions on how to find the port in the code
- - Your **fan may use a different color scheme** for its wire, or have a black color scheme. Be sure to 
-Google a diagram first.
  - You may need to change some variables in the Arduino code depending on your fan's specifications.
    - Try looking up a datasheet
  - This was designed for an Arduino Uno, and should work on one. I don't know about running it on anything else, though.
