This sketch kept crashing - here’s the arduino code.

Serial.begin(9600);
  pinMode(LEDpin, OUTPUT);

void loop() {
//  potentioReading();

   int inByte = Serial.read();   // read it
    Serial.write(inByte);         // send it back out as raw binary data
    analogWrite(LEDpin, inByte);       // use it to set the LED brightness
}

Behaviour that causes the browser to crash:

Pressing any key, or clicking/dragging the mouse key.

Additionally, I’m unclear on a few of these question - to be discussed in 11/02 class.
