## Automating with Cron
To have the alarm start automatically at a specific time (e.g., 6:45 AM on weekdays), you can set up a cronjob.
1. Open your crontab configuration:
```bash
crontab -e
```
2. Add the following line at the end of the file (adjust the paths if your setup differs):
```bash
45 6 * * 1-5 cd /home/pi/workspace/wecker && /usr/bin/python3 wecker.py > /home/pi/workspace/wecker/cron.log 2>&1
```
* `45 6`: Runs at 6:45 AM.
* `* * 1-5`: Runs from Monday (1) to Friday (5). Skips the weekend.
* It ensures the script runs in the correct directory so it can find the audio file.
