Milk Boil-Over Guard
Two steel probe rods sit above the milk. When the foam touches them, the Arduino beeps and a servo lowers the flame.
Adults only
Involves a gas stove and flame.
Not for children. Build at your own risk.
Strictly follow the description given with this video.

How it works
- Rising milk foam touches both steel rods and connects them.
- Rod 1 is on D3 with a pull-up, so the pin reads LOW when the foam joins it to GND.
- The Nano turns the servo to lower the flame.
- The buzzer beeps to call you back to the stove.
