This is to make wiring easier. #include <Servo.h> Servo servo1; //Servos Servo servo2; Servo servo3; const int LED1 = 2; //LEDs const int LED2 = 3; const int LED3 = 4; const int LED4 = 7; const int LED5 = 8; const int button1 = 12; //Buttons const int button2 = 13; int button1Presses = 0; //Button values boolean button2Pressed = false; const int pot1 = A0; //Potentimeters const int pot2 = A1;  const in
