Distance sensor

Powered Up Distance example

This example shows how to read values from the distance sensor.

The following call selects the Move Hub in the simulator, this is only necessary to run this demo without an actual connection to a device...

If you are using a Move Hub then this exemple expects the distance sensor to be connected to port "C". If you are using the Hub -which has only two ports- then you can change the value POWERED_UP_PORT_C to POWERED_UP_PORT_A and connect the sensor to port "A"...

        if value != lastValue
            ; The value is changed!
            lastValue = value
