Projects with this part

• Waterproof Thermometer (Aquarium / Tea)Beginner30 minA thermometer that measures water temperature with a waterproof DS18B20 probe and shows it on a 4-digit display as "24°C". When the temperature leaves the allowed range the buzzer sounds and the display blinks: three fast, high beeps when too hot, a slow, low beep when too cold, so you can tell which by ear alone. It comes set to 23-28 °C for an aquarium; for tea, set the lower limit to 60 °C and it beeps once the tea has cooled enough to drink. It teaches 1-Wire communication and the pull-up resistor, not making the program wait while a reading is taken, and leaving a margin so the alarm does not flicker at the limit. The DallasTemperature and TM1637 libraries are installed from the Library Manager.Open project
