Project Notes

Tin Counter

A project by novaprimexex to count tins as they roll by and detect tins without paper labels.

The Build

Notes

This project is basically to build a chute that would count tins as they roll by and detect tins without paper labels.

The label detection works by runnibg a piece of wire on the floor of the chute and connecting it to the A0 pin. The A0 pin detects tins without labels by reading the voltage on the wire.

If the metal surface of the tin (i.e tins without labels) comes in contact with the wire, there would be a change in the voltage. A change in voltage means the red led would blink once.. one blink for ever labeless tin that passes.

This page is a web-friendly rendering of my project notes shared in the LEAP GitHub repository.

LEAP is my personal collection of electronics projects, usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:

Feel free to borrow liberally, and if you spot any issues do let me know. See the individual projects for credits where due. There are even now a few projects contributed by others - send your own over in a pull request if you would also like to add to this collection.
