Serv-Arm improved

This is an improvement of:

I made a new base for the robot arm to attach a Arduino Nano on a Shield. You can directly atttach the servo motors on the shield, because it has got all the power and ground pins directly at every signal pin. This makes wiring much easyer. Also there is more weight on the ground plate so that the robot arm is more stable while moving

Also I added two knobs for play and pause that fit to my micro switches I used.

And I used smaller 6mm trimmer potentionmeters so I hat to make some adapters that I added here, too. Print more of them at once so that the small axles can cool down before the next layer is added. So they will not bend while printing. There is also a split verion that is printed 90° turned which also could work.


Another thing I added are printable round servo wheels, my servos didn't come with fitting parts.
