<commit_before>#WallBot Version 2

For my next version of WallBot I mounted the sonic sensor onto a servo.

I explain a bit more about the build and the code [here](http://solderspot.wordpress.com/2014/01/12/wall-bot-version-2/)
 
##The Servo

The HC-SR04 sensor is mounted on the servo using double-sided foam tape. Works really well.

I used the Arduino's Servo library to drive the physical servo and my own SS_Servorator and SS_ServoTrim libraries to provide speed control and fine adjustments to the servo pulse timing.<commit_msg>fixed file typo<commit_after>#WallBot Version 2
