I wanted to be able to get information back from Google Earth. It’s already easy to plot information on Google Earth, but getting information back, like the GPS coordinates under the mouse pointer, was another story. Well, I slaved myself to my desk for a few days and figured it out. I created a sample VI program that displays the GPS coordinates of the Mouse over the globe, and captures the coordinates on a left mouse click. It then feeds them back into Google Earth as a point.

Here is a video of the LED Lab Coat with the better PWM code. If you are interested in how I programed 8 channels of software PWM, here is the source available for download.

Part 2 of my documenting of my robot project focuses on the just completed “Smart Motor Controller”. I call it a smart controller because, unlike other motor controllers on the market, mine utilizes feedback from the motors to precisely set wheel speeds and report back how far the robot has traveled.The brain of the controller is an Arduino Pro mini, pictured in this post. The actually driver H-bridge  is a Ardumoto from SparkFun.
