Photo Interrupter Sensor

1. Write standard firmata to the device

Uploading Standard Firmata to Arduino Open Arduino IDE. File > Examples > Firmata > StandardFirmata.

Tools > Board > your board Tools > Serial Port > your port Click Upload button. if you use WSL, you need to follow this

2. Run the PhotoInterrupt sensor

index.tsx

import { Board, Led, PhotoInterrupter, render} from "edison"
import React, {useState} from "react"

const App: React.FC = () => {
  const [isOn, setIsOn] = useState(false)

  return (
    <Board port={'/dev/tty***'} baudRate={57600}> 
      <PhotoInterrupter
        pin={8}
        triggered={() => {
          setIsOn(true)
        }}
        untriggered={() => {
          setIsOn(false)
        }}
      >
        <Led
          pin={13}
          isOn={isOn}
        />
      </PhotoInterrupter>
    </Board>
  )
}
render(<App />)

This program will blink the LED when the photo interrupter sensor is run.

3. execute the program

$ npx vite-node index.tsx 

You can use <PhotoInterrupter >
