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 ...

I bought a Ninja Block ... a Arduino + Node.js server thing that runs on the device to send the data from your devices (in my case, just two 433Mhz temperature/humidity sensors) to Ninja Blocks ...

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 ...
