Summary of COIN SORTER IS ELEGANT AND BEAUTIFUL
Summary: Daniele Tartaglia built an elegant coin-counting machine that vibrates coins from a hopper, feeds them through a size-based sorter that channels different denominations, counts them with infrared sensors connected to an Arduino, and routes coins through a decorative maze into sorting bins. The device provides steady feeding, physical sorting by dimensions, and electronic counting for convenient change counting.
Parts used in the Coin Sorter:
- Hopper for holding coins
- Vibrating motor
- Feeder slot mechanism
- Size-based coin sorter (mechanical flicking channels)
- Infrared sensors
- Arduino
- Routing maze for coins
- Sorting bins at the bottom
- Wiring and mounts for sensors and electronics
Counting change is a great way to teach children about mathematics and money, but it grows tiresome for those of us that have passed the first grade. Thus, a machine should the job, as [Daniele Tartaglia] demonstrates.
A vibrating motor is used to shake a hopper full of coins, letting them fall through a feeder slot into the machine at a steady rate. They then go through a size-based sorter, which flicks the coins into a different channel depending on their physical dimensions. The coins are counted via infrared sensors wired up to an Arduino, and then pass through a rather lovely maze on their way down to sorting bins at the bottom of the machine.
It’s a tidy build, and a great thing to have if you regularly find yourself needing to count change. We haven’t seen too many coin counters before, but we have seen a laundromat given an overhaul with some hacker skills. Video after the break.

- How are coins fed into the machine?
Coins are vibrated from a hopper by a vibrating motor and dropped through a feeder slot at a steady rate. - How does the machine sort coins by type?
A size-based mechanical sorter flicks coins into different channels depending on their physical dimensions. - How are coins counted?
Infrared sensors wired to an Arduino count the coins as they pass. - What role does the Arduino play?
The Arduino receives signals from the infrared sensors to count the coins. - Do the coins go directly to bins after counting?
After counting, coins pass through a decorative maze and then into sorting bins at the bottom. - What provides the steady feed rate of coins?
The vibrating motor shaking the hopper provides a steady feed rate through the feeder slot. - Is the sorter primarily mechanical or electronic?
The sorter uses mechanical size-based flicking for physical separation and electronic infrared sensors with an Arduino for counting. - Is the build intended for frequent use?
Yes, it is presented as a tidy build useful for those who regularly need to count change.
