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:
```

i2c scanning all the devices can confuse some of them,
such as the OV* camera's. Better to selectively scan just the ones
we want to know about, plus, it's also faster.
M5Stack-Fire board detection should be:
i2c0 = I2C(0, sda=Pin(21), scl=Pin(22))
if {0x68} <= set(i2c0.scan()): # IMU (MPU6886)
return "m5stack-fire"
But there are some pin incompatibilities between ESP32 and ESP32-S3 boards that don't allow I2C scan.
- Natural orientation: camera on top, USB ports on bottom
- OV3660 camera works (but colors are off and it breaks the touch input)
- Improve board detection
