Question

如何由电脑通过arduino控制步进电机

Answer 1

int val=0;
int i=0;
int Pin0 = 8;
int Pin1 = 9
;int Pin2 = 10;
int Pin3 = 11;
int step = 0;
int stepperSpeed = 1;

void setup()
{
pinMode(Pin0, OUTPUT);
pinMode(Pin1, OUTPUT);
pinMode(Pin2, OUTPUT);
pinMode(Pin3, OUTPUT);
Serial.begin(9600);
}

void loop()
{
val=Serial.read();
if (val=='a')
for(i=0;i<100;i++)
{
digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, HIGH); delay(stepperSpeed);
digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, HIGH); delay(stepperSpeed);
digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, LOW); delay(stepperSpeed);
digitalWrite(Pin0, LOW); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, LOW); delay(stepperSpeed);
digitalWrite(Pin0, LOW); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); delay(stepperSpeed);
digitalWrite(Pin0, HIGH); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); delay(stepperSpeed);
digitalWrite(Pin0, HIGH); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); delay(stepperSpeed);
digitalWrite(Pin0, HIGH); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, HIGH); delay(stepperSpeed);
}

if (val=='b')
for(i=100;i>0;i--)
{
digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, HIGH); delay(stepperSpeed);
digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, HIGH); delay(stepperSpeed);
digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, LOW); delay(stepperSpeed);
digitalWrite(Pin0, LOW); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, LOW); delay(stepperSpeed);
digitalWrite(Pin0, LOW); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); delay(stepperSpeed);
digitalWrite(Pin0, HIGH); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); delay(stepperSpeed);
digitalWrite(Pin0, HIGH); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); delay(stepperSpeed);
digitalWrite(Pin0, HIGH); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, HIGH); delay(stepperSpeed);
