### How to use ### How to use
1. Connect the Arduino to the fan according to this diagram: 1. Install dependencies using `pip install -r requirements.txt`
2. Connect the Arduino to the fan according to this diagram:

2. **Set the port variable** 3. **Set the port variable**
1. Instructions for finding the port are in the Python code. 1. Instructions for finding the port are in the Python code.
3. Upload `Arduino/rx_speed.ino` to your Arduino Uno, then run `Python/tx_speed.py`. 4. Create a script to run this every 10 seconds
1. Make sure not to run the Python file until the Arduino sketch is done uploading! It should only take a few seconds. 1. Use a text editor to create a script called `every5secs.sh, and add the code below.
5. Revel in your success! 2. Make a note of where you saved the script, and remember to change `/path/to/tx_cron.py`
1. If you plan to use this constantly, make sure to create a service that starts the Python code on boot. ```bash
# This runs the tx_cron.py every 10 seconds
i=0
while [ $i -lt 6 ]; do # 6 ten-second intervals in 1 minute
python3 /path/to/tx_cron.py & #run your command
sleep 10
i=$(( i + 1 ))
done
```
4. Create a cron job
1. Run `crontab -e`
2. Add this line to the bottom of the file: `* * * * * python3 /path/to/every5secs.sh`
1. Remember to change the path to your script!
3. Save and exit with `Escape`, `:wq`, `Enter`
