It would be much easier to increase the number of servos if the author had use arrays instead of four different names.
Did you need the OLED display?
The sketch can only store eight positions. Is that enough? How many positions do you need to store?
Here is the original sketch:
#include <Servo.h>
#include <OLED_I2C.h>
//define the servos
Servo servo1;
Servo servo2;
Servo servo3;
Servo servo4;
OLED myOLED(SDA, SCL);
extern uint8_t SmallFont[];
//define the buttons
const int button1 = 12;
const int button2 = 13;
//define variable for values of the button
int button1Pressed = 0;
boolean button2Pressed = false;
//define potentiometers
const int pot1 = A1;
const int pot2 = A2;
const int pot3 = A3;
const int pot4 = A4;
//define variable for values of the potentiometers
int pot1Val;
int pot2Val;
int pot3Val;
int pot4Val;
//define variable for angles of the potentiometer
int pot1Angle;
int pot2Angle;
int pot3Angle;
int pot4Angle;
//define variable for saved position of the servos
int servo1PosSave[] = {1, 1, 1, 1, 1, 1, 1, 1};
