Test Code 7:
*******************************************************************************************************************************
#include <Servo.h> // add the servo libraries
Servo myservo1; // create servo object to control a servo
Servo myservo2;
Servo myservo3;
Servo myservo4;
int pos1=80, pos2=60, pos3=130, pos4=0; // define the variable of 4 servo angle and assign the initial value( that is the boot posture
angle value)
const int right_X = A2; // define the right X pin to A2
const int right_Y = A5; // define the right Y pin to A5
const int right_key = 7; // define the right key pin to 7（that is Z value）
const int left_X = A3; //define the left X pin to A3
const int left_Y = A4; // define the left Y pin to A4
const int left_key = 8; // define the left key pin to 8（that is Z value）
int x1,y1,z1; // define the variable, used to save the joystick value.
int x2,y2,z2;
int s1,s2,s3,s4;
int jiyi1[20]; //define 4 array, separately used to save the angle of four servo.
int jiyi2[20]; // （array length is 20，namely can save angle data of 0~20 servo）
int jiyi3[20]; //if need to save more data, just change the number 20 to be more larger number.
