This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

Of course, many different types of distance measuring sensors exist but not all sensors are the same. Each sensor has its own advantages and disadvantages. At its most basic level, a distance ...
