After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

It’s an interesting take on a 3D scanner. He used a stepper motor to rotate the object being scanned, and an Arduino for control, but the real novelty is the way he used the sensor.

This post is a review of some commonly available distance measuring sensors in general and the Sharp GP2Y0A21YK0F in particular. Well, let us get started… Distance Measuring Sensors Of course, many ...

The idea is pretty neat, so [Ivan] decided to implement it for mains devices by making this proximity switched outlet box. A Sharp GP2D12 infrared distance sensor is the key to the system.
