BoBShield: actuatorWrite() method

[gergelytakacs]

The actuatorWrite() method should:

• Write the angle to the the servo motor
• The angle should come as a floating point number
• The 0 position should be the horizontal position
• Maximum and minimum angles should be enforced in order to prevent damage to the tube or other parts of the shield
• The angles should be double checked and verified so that we know that they are allright.

This is useless.

• we call it actuatorWrite() (1)
• The contents of this do not make any sense. This method should take a floating point number in degrees and set the servo to the correct value. End of story.. (2-3)

• As per AutomationShield API Style Guide #42, please call the servo pin (and define it in the header) as BOB_UPIN. This is just to keep the API consistent.

I rhoughly understand the idea, but please do comment your code...

Also, can you (maybe here is enough) explain how you got all these values?

Also, why int?
