This isn’t about connecting a temperature sensor in your Arduino. This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno ...

It’s done by monitoring conditions like temperature ... used by [934Virginia’s] Arduino library to compare the difference between your target climate and actual sensor readings in your greenhouse.

Arduino’s new Plug and Make Kit continues in this vein. SparkFun’s Quiic connector allows you ... a buzzer, and sensors covering temperature and humidity, distance, and a gyroscope.
