6DOF robot arm added pololu servo driver, you can now connect to it with serial communication. I'm printing all my modifications, do the testing and GO....
If you want you even don't need a arduino, It can connect directly to a pc with serial communication. I will use an arduino controller to control the neopixel led and some in and outputs from the arduino board to command or recieve some things afterwards.
The robot arm can be controlled with the graphical GUI controler with FULL inverse kinematics!!! When all parts are assembled and tested I will put everything online!
