some screws M3,M2 and nuts

arduio code:
int x;
const int buttonPin = 2;
int buttonState = 0;

void setup()
pinMode(6, OUTPUT); // Enable
pinMode(5, OUTPUT); // Step
pinMode(4, OUTPUT); // Dir
digitalWrite(6, LOW); // Set Enable low
pinMode(buttonPin, INPUT);


void loop()
buttonState = digitalRead(buttonPin);


if (buttonState == HIGH) {

digitalWrite(6, LOW); // Set Enable low
digitalWrite(4, HIGH); // Set Dir high

for (x = 0; x < 4000; x++) // Loop 200 times
  digitalWrite(5, HIGH); // Output high
  delayMicroseconds(300); // Wait 1/2 a ms
