error: 'voltage' was not declared in this scope

Downloaded the ino file and attempted to push it to the Arudiuno, However I'm getting the subject error. Any thoughts?

+1, code on main branch doesn't compile

I had the same problem. However, the source code in the pdf file you need to download has the missing line (after the int batvalue line):

int batvalue = analogRead(A7);
float voltage = batvalue * (10 / 1024.0); // Calculating Percent Of Battery

Also, my servos had no stops to calibrate with, so I modified the code to set them to 90 degrees and leave them there while I attached the two pieces to the servos. My unit now tracks light.

I also added a little command line interpreter so I could give it commands over the serial port to enable/disable the servos, force them to 90 degrees, or turn off/on the readings

@dkgoodman mind sharing your code/changes?
