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 ...

The final data output is in a 12-bit resolution, SPI-compatible, read-only format. The clever chip has an open thermocouple detection feature as well. For quick prototyping, it’d be better to use ...

Using motion ... passes in front of a PIR sensor it detects the change in background temperature and then triggers an output voltage. This voltage can be read by an Arduino digital input and ...
