My original problem was communication between the second arduino and the roboclaw. I posted a pdf of the roboclaw and stated that slide 26 explained the 128 and 255 numbers for channel 2. I was wanting to either apply 128 to the actuator(full reverse) or 255(full forward) depending on what the value of the pot (the 'B' part) was. Well, using BMSerial and trying to write to the roboclaw was obviously not working as I could not get it to work.
Now, what I just posted was testing the output . I have 3 pots hooked up to arduino1 that sends the values to arduino2 through xbee. I also distinguish which pot it was using 'S', 'B', or 'G'. When I was testing earlier, I would ONLY move with the 'B' pot and it would record but it was also recording 'G' pot also when that one was not even being touched. As you can see, it records 'B' correctly and it is suppose to apply the actuator depending on the value of the pot.
