If you use only publish the encoder data, then yes. Else, if you directly publish the odom data from the arduino, you don't.

No, if you just want to run your code that publishes stuff from arduino, you do not need any other package...

If you want to test that the messages published by your arduino are correctly published you can use (in another shell on your host PC)

rostopic echo /your_topic

or

rostopic hz /your_topic
