This Arduino Project Hub guide shows you how to set up an AMG8833 thermal camera with an OLED display for an Arduino. This sensor is relatively complex to ... making them easy to wire up and code.

The pulse sensor uses a piezo element pressed against a fingertip to detect changes in pressure resulting from blood flow. It can be picky about placement, but finding sweet spot can yield ...

The Arduino Sketch (code) uses the external interrupt (int 0) on Arduino’s digital pin 2 (D2). This is used to read the output pulses coming from the water flow sensor. When Arduino detects the pulse, ...
