Minimal script working servo are not working

Hi All, I have now managed to get the Arduino to talk to MRL properly, I can run the minimal script and the audo works fine, the Arduino flashes away but the servo refuses to moves. I have the control pin on PIN 3 of the Arduino as suggested in the script, the Sliders do not operate the server either. Tried several servos, what do you think I am missing here folks - Thanks

Do you have the  MRL comm

Do you have the  MRL comm file downloaded on the Arduino ?

What version of MRL do you

What version of MRL do you use? Because with the last 1842 I have the same problem

Currently using 1.0.118 as I

Currently using 1.0.118 as I don't have any success at all with the newer versions. Using this version I can get a bit further and the servo respondes but then crashes. Could anyine suggest a combination of MRL and MRLcomm for the Arduino. That would be very helpful. Many Thanks for all your help. Getting a bit further every time.

Power problem ?

This could perhaps be a power problem. Servos draw more current than the Arduino can supply, so they need to be powered separaltey, with a common ground. You can see how you need to connect the servos from the diagram a bit down on this page:
