4.1.6 is pretty old now. 4.1.16 is the current version. I dont beleive 4.1.6 had the CRC16 checksum change yet so you will need to use the older sum'd checksum command format. With pots Velocity control is usually not very useful. To low a resolution for meaning full velocity information. I recommen...

When you press any button on the roboclaw it stops controlling the motors. So the PID loop has stoppedm hense the noise stops. It sounds liek your PID tunning is too agressive(probably by alot). Before trying to tune the motors you need to determine why the motors channels are not working independen...

I beleve you have the latest arduino library we just uploaded this past week. If you are using pins 0 and 1(the hardwares serial pins, you need to change the constructor to use the Serial object instead of creating a software serial object. Please see the comments in the bare minimum example to see ...

IonMotion only works with the USB models. Do you know what firmware version is on your board? If its much older than 4.1.16(which it probably is since we havent sold non-USB models in a while now) I recommend you send it in for a firmware update. When your position is falling short by alot it usuall...

The arduino commands are listed in the Roboclaw.h file included with the library. It shows the syntax of each command. The arduino commands where named to closely match the Roboclaw manual packet serial commands.

If you have a 2x5A without USB you have a very old version of the board. The only way to use it with the latest software is to send it in and get its firmware updated to the latest version. Otherwise you need to use the old packet serial communications(eg with the simple sumkming checksum instead of...

We have replaced the old Arduino library for Roboclaw with an updated version. It is available from the same download links as the old version. This version has been tested with Arduino 1.6.8. Please see the example code for the new constructor syntax. We are now using the builtin SoftwareSerial lib...

I believe the problem will be resolved if you download our latest arduino library for Roboclaw. I just updated it on the server. We are now using the latest SoftwareSerial libraries included in the Arduino software(tested with Arduino v1.6.8) which have much better bit rate timings than the old news...

Yes, you can power the Arduino from the 5v on the Roboclaw. Just connect the Arduino 5v and gnd to 5v and gnd on the roboclaw.

The pins used for S4 and S5 on the older version roboclaws are not connected to anything. I would not recommend it but you could technically wire something directly to those pins on the main processor.
