Two buttons comand "Focus" of the microscope. 1 button changes color and 1 changes brightness of the light for the object. Stepper motor driver is connected to pins 7 and 8; RGB LEDs connected to pins 11, 10, 9; LED comand buttons are connected to pins 2 and 3; and stepper motor comand buttons are connected to pins 4 and 5
