Distance Sensor

This function is used when using distance sensors.

Distance.Read(trigger, echo) - Uses ultrasonic sonic sensor to read distance.
trigger: The pin number that is connected to trigger (pulse) signal
echo: The pin number that is connected to echo signal, use -1 for single pin
Returns: Distance in centimeters

Most sensors need 5V to work.

This example will read distance, using pin 0 for trigger and pin 1 for echo pin.

while True:
    x = duelink.Distance.Read(0, 1)

    if x > 0:
        print(x)

    time.sleep(0.1)

while (true) {
    let x = await duelink.Distance.Read(0, 1)

    if (x > 0)
        console.log(x)

    await Util.sleep(100)
}

while (true) {
    var x = duelink.Distance.Read(0, 1);

    if (x > 0)
        Console.WriteLine(x);

    Thread.Sleep(100);
