Raspberry Pi Pico Tea Thermometer (DS18B20 + TM1637 + Buzzer)

Let the Pico tell you when your tea is ready to drink! We are building a thermometer with a Raspberry Pi Pico that measures the tea in your glass. A waterproof DS18B20 probe goes into the tea, and a TM1637 display shows the temperature and the time left until it is drinkable. At 65 degrees the buzzer plays a tune, and it warns you if the tea gets cold.
