5. Making the fingers move

To begin on your own…

There is a design one is suggested to start with (in the Tinker CAD) presented on Fig. 42: 

• Simply take a virtual UNO and a virtual servo-motor. 
• Connect power supply and ground from the UNO board to corresponding pins of a servo-motor, and PWM marked output of the UNO to the “Signal” pin of a servo-motor.  Create a program rotating the servo motor to some position and back.
