## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA5735:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA5735:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

We have various [PCB-mount rotary encoders in the shop](https://core-electronics.com.au/components/rotary-encoders.html), great for making interfaces where you may want to spin a knob around to select a value. These large knobs are also encoders, but very large - like hand-sized! They're used for controlling CNC machines 'manually' - there's 100 ticks per rotation so each rotation can easily align with a centimeter or inch. But they're also really nice for any time where you want a large, 360-degree rotation, tactile interface.

Unlike PCB-mount rotary encoder, these encoders are not soldered directly to a board. Instead, there are screw terminal blocks on the back to connect wires. Provide any DC voltage to **VCC** (for the pullup/positive voltage), and **ground**, and read **A** and **B** for the grey-code pulses. Once wired up, [it works with any rotary encoder tutorial](https://learn.adafruit.com/search?q=rotary%2520encoder).

Rotary encoders are useful as rotation sensors or selectors and look similar to potentiometers. However they are not like potentiometers at all, so it's important to realize the difference! These rotary encoders rotate all the way around continuously and are divided up into 100 'segments'. Each segment has a clicky feeling to it, and each movement clockwise or counter-clockwise causes the two switches to open and close. There is no way to know what the current 'position' is - instead you would use a microcontroller to count how many 'clicks' left or right it has been turned. If you need to detect rotational 'position' a potentiometer would be a better choice.
