+# SetBrightness
+
+I have a keyboard which allows for special keybindings and it has a scrollwheel. I have the ability on this keyboard to
+be able to turn up or down the volume with the scroll wheel but not the brightness on my laptop. With these two programs
+that are generated from this Solution, I can call each program to set the brightness of my laptop screen. I set each up
+to be able to take one parameter as the amount you would like to increase or decrease the brightness. If no parameter is
+passed, then it is increased or decreased by 10%. I also created a shared library in order to reduce the amount of
+repeated code required for each executable to work properly.
+
+Finally, since all these programs do is turn up or turn down your brightness, there is no user interface.
