The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format that can be processed by the microcontroller. Here, we are feeding the input voltage ...

Surprisingly enough, the sensor package consists of a sensor driver module in addition to the original sensor. The LMV358 IC-based module provides a three-pin interface to connect with Arduino (or any ...

The Arduino slowly scans the sensor in a grid, taking readings along the way. A Processing application then takes each reading and compiles the final image.
