hi can anyone help with the configeration of the a hc-sr04 ultrasonic sensor as the example code I've adpted will only give me 17 or 0 output through a serial port.
Please see Below :

Comment:

This example program is configured to measure approximately 1.5-2m (150 - 200cm) from the sensor.

If much shorter distances are used, parameters will need to be changed.

Allows the potentiometer to be used to set the threshold level:

sense = sense / 20

Hi willow,
Perhaps a starting point would be this whole thread
If you do try the flowchart and get stuck then let us know.

Hi
The sensor is working ok with the arduino ping sketch example ,but it seem's more difficult to make it work on the flowcode 6 software ,the distance I'm working with is about 30-150mm max.
