seveibar/keyboard-sample

A tscircuit package created by seveibar.

Usage: For "@tsci/seveibar.keyboard-sample": 1. Import the component: ```tsx import KeyboardSample from "@tsci/seveibar.keyboard-sample" ``` 2. Use the component in a React-like circuit design: ```tsx <board> <KeyboardSample sampleNumber={3} /> </board> ``` The component takes an optional `sampleNumber` parameter to define the grid size of the keyboard matrix (defaults to 2). It automatically generates a keyboard matrix with keys, diodes, and traces connecting to a Pico2 microcontroller.
