Arduino rosserial not updating (not in-sync) with ROS movements [closed]

edit

Hello,

I am trying to make a 3 link robot arm (with 3 steppers) move in a single plane. I am facing some problems when interfacing it with my Arduino Uno.

The robot -arm moves, but sometimes it goes out of sync and it does not move to it's final position for the corresponding movement in ROS. I have debugged the issue and these are the prints from ROS publisher.

The final position should be 3 , but looking at the message published from the arduino, the final value is 1430.

Is this a possible problem of the arduino not able to receive all the messages on time? My ros piblisher works at 10Hz(max) and my arduino loop at 50Hz.
