Read ultrasonic sensor value with specified wait.
Return the ultrasonic sensor distance value. Since an ultrasonic sensor is an I2C digital sensor its value cannot be read using the standard Sensor(n) value. The port must be configured as a Lowspeed port before using this function.
|port||The port to which the ultrasonic sensor is attached. See the Input port constants group. You may use a constant or a variable. |
|wait||The number of milliseconds to wait before querying the sensor. You may use a constant or a variable. |
