Go Stone Sorter Kit for Arduino – Automatic Black & White Sorting Machine, Laser-Cut Wood
Drop black and white Go stones into the tube and this wooden machine detects each colour and sorts them into two trays.
Designed by Mematrix Lab
Description
A machine that sorts black from white
Stack black and white Go stones in the clear tube and press start. An infrared sensor checks each stone as it drops, and a servo-driven gate flips it into the black tray or the white tray. You can start and stop it with the button, or set it to run for a preset time. It is a compact, satisfying introduction to sensors, servos and simple automation.
What you'll learn
- How an infrared reflective sensor tells dark from light
- Driving a servo to make decisions
- Program flow: start/stop buttons and timers
- How sorting machines work in factories
What you'll do
- Assemble the laser-cut frame, tube and sorting gate
- Mount the sensor, servo and controller
- Plug in the wires
- Load the stones, press start and watch it sort

Shipping
Standard shipping: $9.00 for the first item, +$1.80 for each additional item. Free shipping on orders over $260.
We ship worldwide, by default with economical international post (UPU / China Post small packet) to keep shipping costs low. Orders are usually handed to the carrier within 2–5 business days, and economical international post then takes about 10–30 business days to arrive; these are estimates, not guarantees. Delivery time depends on the destination and on postal and customs handling. If you need your order by a certain date, email us before ordering: faster shipping can be arranged, with the extra cost charged at the carrier's actual rate. Items that contain batteries or magnets are marked on their product page and ship by a special carrier line; some countries and regions cannot be reached by that line, and if yours is one of them we refund the order in full.
Batteries & magnets
This item contains, or may contain, batteries or magnets (for example in a motor, speaker or rechargeable battery). Ordinary postal parcels with such items may not pass security screening, so it ships by a special carrier line, and its price includes a $10 surcharge for this. Some countries and regions cannot be reached by this line. If yours is one of them, we will email you and refund your order in full.
Customs & duties
Import duties, taxes and customs requirements depend on the destination country, the shipping route and the local customs office, so we cannot say in advance whether any will apply to your parcel. Customs may hold a parcel, ask for more information, or ask for duties or taxes to be paid, even when the declared value is correct. If you have a question about your country, email us before ordering.
