All went well

Follow up - error report ultrasound sensor not supported on this device tnx for help guys

Hello @Hobb0,

Not all the ARC controls are supported yet for Arduino, Raspberry Pi, etc. It seems that the Ultrasonic is one of those controls.

I will try my Ultrasonic sensor later, the sharp sensor works

I did test the Ez -robot Ultrasonic sensor with the arduino tonight, not compatible

Plz send urgent request to developers - this is a great system but I really need this function - many many tnx guys @ezang n @ Jeremy both many thnx for looking

Here is a site I use - example of arduino and ultrasonic sensor

hope this helps

Tnx @ezang - nice link but ARC throwing error msg. ultrasound sensor not supported yet for Arduino
