Setup the "Buzzer" and play intro and outro ;) Don't know if "I2S audio" is possible.

Battery "settings": I tested to run ODROID-GO as long as it's possible. The min. raw ADC value on
ODROID-GO i have seen is 210. So update the calculation.

Fix the boot by moving ODROID-GO below `fri3d_2024` because the device will hard crash on
`fail_save_i2c(sda=9, scl=18)` like:
```
