Equatorial mount power tracking part control motherboard

Make an equatorial mount to track the stars. At present, we will build the power part first. With subsequent improvements, we hope to achieve the effect of a thousand-yuan machine. The cost of this equatorial mount should be controlled within 100 yuan!

void setup() {
  // put your setup code here, to run once:
pinMode(2,OUTPUT);//STP
pinMode(3,OUTPUT);//DIR
pinMode(4,OUTPUT);//EN
pinMode(5,OUTPUT);//ms1
pinMode(6,OUTPUT);//ms2
pinMode(7,OUTPUT);//ms3
digitalWrite(5,LOW);
digitalWrite(6,LOW);
digitalWrite(7,LOW);
digitalWrite(4,HIGH);
//电机工作 8细分模式
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(3,HIGH);
for(int i=0;i<1000;i++)
{
  digitalWrite(2,HIGH);
  delay(10);
  digitalWrite(2,LOW);
  delay(10);
}
  digitalWrite(3,LOW);
  delay(10);
  for(int i=0;i<1000;i++)
{
  digitalWrite(2,HIGH);
  delay(10);
  digitalWrite(2,LOW);
  delay(10);
}

}

The production process of the star chaser will be released in the future, so look forward to the results.
