Controller Ar-1202Mg Servo With ARC

Skip to comments   Jump to end

Hello,

PLEASE describe to me exactly how to control an AR-1202MG servo using an EZ-B v4 wifi controller.

AS of now, when I plug in the servo to D0 and use the vertical servo control, the servo does not move and an LED quickly blinks. I can feel the servo and I know it is receiving power. Sometimes the EZ-B resets itself and I have to reconnect.

Please advise on what to do.

Sincerely,

@david

No solutions are too simple here in the ezrobot forums.

Take it from experience, it's often the littlest things that can get cha.

Looking at this problem from another standpoint, we have 2 users here in the forums with PowerHD servo experience @robotMaker and @charleybot Maybe you can send them a message. If the servos worked with the EZ-Bv3 they will work with the v4 as well.

The company that imports them and/or makes them is selling the servos on ebay... I messaged them this morning to find out more details on using them... When and if they get back to me then we'll know for sure....

@Dave... Just in case you are still paying attention to this thread... I finally got a reply from the seller on eBay of these servos and just as I suspected he confirmed that they are just regular analog servos. They can be controlled like any other hobby servos via an arduino, radio or ezb....

Hello,

To answer your questions.

  1. I Have modified the power to only supply 6V to the servo, after the digital port.
  2. I have tried both vertical and horizontal controls and have changed the min max settings on both the D0 and D1 ports.
  3. I have modified an unused servo, for the 6 volts, and tried using it on D0-D5. Also with no movement.
  4. I am sure I am connecting to the EZ-B because other controls work properly. I can play an audio file or check the settings.

I understand the seller of this item has told us they are standard servos and should work just as any other servo. I believe this is true.

So I guess I am wondering........what else could it be that is preventing this servo from moving?

David... Have you considered maybe the servo is not working?... Is there anyway to test it using a remote control RC radio or an arduino?

#22  

I sure hope not. So far I have tried 2 of the 9 servos I have bought. Both the 2 I have tried do not work.

I hope I did not get a whole batch of baddies......

Sorry David... Then the servo is probably good... It should work. I am not sure what else to suggest....?

David,

See post #17. I don't think you have answered the question about your power supply. Your symptoms really sound like high in-rush current required by the servos and a power supply unable to handle that (the resetting of the EZ-B is classic for that).
