This is an customized version of the depricated Sparkfun Danger Shield v17
Changes.
- added foot prints for optional pull-ups to buttons. I have run across several UNO's who's internal pull-ups do not work.
- Added 3 pin header for Servo, driven by PWM on D9, which is in parallel to Cap Sense.
- added USB1881 Hall effect sensor, in parallel to TMP36. As TMP36 is out of stock at SFE.
