I have tried to make a program using "struct" for 6 button state and one angle input signal to control using 6 LEDs and one Servo and its working fine
But problem is that when i add one more input signal that time output become erratic and output is not getting as per program.Please help to modify the program.Program mentioned below.(with 7 button states and an angle inputs.).
