I have calibrated the Continuous Rotation Servos on my Adventure Bot according to the tutorials and all the tests work as expected. But I can only move one at a time with the arrow keys and cannot program any movement with blockly. Any suggestions about what I have misunderstood will be appreciated.
Upgrade to ARC Pro
Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.
Heres a great activity course from EZ-Robot on how to use your robot: http://www.ez-robot.com/Tutorials/Lesson/132?courseId=7
If I set both speed controls to (say) the top, nothing happens, the servos do not respond to any Arrow Key but If I then click on a slider and start moving it the other slider drops immediately to 0 (hence the setting you have highlighted where you can see that the RH slider is being moved down while the LH has dropped to 0) and the chosen servo begins to respond. I can then control each servo separately provided the other is at 0. I can't move the sliders to a set position together and get a response. One slider has to be at 0 for the other to work.
(which I chose because I want to play with Arduinos etc.)
