Overview
This sensor SharpGP2Y0A21YK, boasts a small package and very low current consumption, takes a continuous distance reading and returns a corresponding analog voltage with a range of 10cm (4") to 80cm (30"). It can be used in TVs, personal computers, cars and so on.
Features:
- Grove interface compatible
- Wide supply voltage range: 2.5V-7V
Interface:
The sensor is quite small and use a tiny connector called a JST connector. These connectors have three wires: ground, vcc, and the output. Because the sensor fires continuously and don't need any clocking to initiate a reading, it is easy to interface with any microcontroller.

While taking photos today is normally a digital affair, there is a wealth of visual information stored on film negatives. Digitization is possible, but it tends to be rather time-intensive, so photographer/hacker Seckin Sinan Isik decided to automate the process. His setup uses a film carrier augmented with a stepper motor and belt drive to advance the 35mm film under a tripod-mounted digital camera. This is controlled by an Arduino Nano, with the camera’s view shown via a video capture device on a nearby computer. In one mode, the user can adjust the film position semi-manually using pushbuttons, then scan the negative. The whole process can also be automated, with a Python computer vision routine. More details on the project can ben found in Isik's PetaPixel article here.
