Automatic shiny hunter servo Jitter problem

Using Arduino Interfacing w/ Software on the Computer
1

Hello Guys,

i bought a shiny automatic hunter it uses a arduino nano with nano shield and 5 servos.

my problem is after some resets sometimes 100 or 500 - 1500 the servo that use most ( to press a and y butoon on the 3ds XL) it begins to jitter.

i tryed to use a new servo and another pin on the shield but nothing works in the long run.

here is the code maybe you can help. and is there normal that a pieeeeeeeep signal sound is always to listen ? :slight_smile:

<#include <Servo.h>

#define NEWLINE '\n'
#define READ_LIGHT 'B'
#define READ_LIGHT_ADVANCED 'C'
#define LIGHT_LOW 'L'
#define LIGHT_HIGH 'H'
#define HOLD_UP '8'
#define HOLD_DOWN '2'
#define HOLD_LEFT '4'
#define HOLD_RIGHT '6'
#define PRESS_UP 'e'
#define PRESS_DOWN 'd'
#define PRESS_LEFT 's'
#define PRESS_RIGHT 'f'
#define BUTTON_A 'a'
#define BUTTON_B 'b'
#define BUTTON_X 'x'
#define BUTTON_Y 'y'
#define RELEASE_ALL '0'
#define SOFT_RESET_1 'S'
#define SOFT_RESET_2 'Z'
#define WONDER_TRADE 'W'
