This is a basic code and breadboard schematic for 2 button control of a micro servo.
Prior to this code I was unable to find a working code to control a servo motor by incremental control using push buttons instead of utilizing a potentiometer. This code isn't perfect, but it is functional. The LCD is used to visualize the position of the servo motor in degrees and to troubleshoot potential problems.
