## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=LBH082:1` (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/LBH082:1.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

The light sensor Bit can turn your circuit on and off by detecting the brightness or darkness of the environment they are in. control your circuit's with light! The amount of light shining on the sensor will change how your circuit behaves. It's a great way to activate your circuit, and is perfect for alarms!

The light sensor is similar to a dimmer. It measures how much light is shining on it and activates the Bits that follow it based on the amount of light. It has two modes: "light" and "dark". As of the environment gets brighter, the Bits that follow the sensor will gradually turn on. The light sensor also has a "dark mode" that allows it to work in reverse. As it gradually gets darker the Bits that follow will gradually turn on.

Use the small slider on the board to adjust how much light it takes to change the signal. Sliding right increases sensitivity, left decreases it. Older versions of this Bit have a small screw dial instead of the slider. Use the included purple screwdriver to turn this dial.
