Project Notes

Tin Counter

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

The Build


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 just my personal collection of projects. Two main themes have emerged in recent years, sometimes combined:

  • electronics - 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
  • scale modelling - I caught the bug after deciding to build a Harrier during covid to demonstrate an electronic jet engine simulation. Let the fun begin..
To be honest, I haven't quite figured out if these two interests belong in the same GitHub repo or not. But for now - they are all here!

Projects are often inspired by things found wild on the net, or ideas from the many great electronics and scale modelling podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know (or send a PR!). See the individual projects for credits where due.
