Servotester
This is an Arduino based testing and calibration device for servo motors.

I use it for testing the maximum usable angles of the motors in my InMoov robot.
For more details please have a look at the corresponding GitHub project:

There you can find additional information like what parts are needed, how to program the device and how to assemble the device.
Have fun!
