This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

This Arduino Get Started guide shows you how to set up a capacitive soil moisture sensor with an Arduino. Like many Arduino sensors, soil moisture detectors only have three pins: GND, VIN, and data.

This tutorial on thermopile sensors for contactless temperature measurement offers insights for using them in real-world ...
