Hello Michael,
Thank you for your reply.
Pin 12 is for setting the forward of high level motor and the reverse of low level motor of Motor A; Pin13 is for setting the forward of high level motor and the reverse of low level motor of Motor B. E1 is connected to Pin 10 and E2 is connected to Pin11, which is for PMW, can control the speed of Motor A and Motor B.
Here is the Program code for you:
int E1 = 10;
int M1 = 12;
int E2 =11;
int M2 = 13;
void setup()
{
pinMode(M1, OUTPUT);
pinMode(M2, OUTPUT);
}
void loop()
{
{ int value;
for(value = 0 ; value <= 255; value+=5)
{
digitalWrite(M1,HIGH);
digitalWrite(M2, HIGH);
analogWrite(E1, value); //PWM调速
analogWrite(E2, value); //PWM调速
delay(30);
}
delay(1000);}
{ int value;
for(value = 0 ; value <= 255; value+=5)
{
digitalWrite(M1,LOW);
digitalWrite(M2, LOW);
analogWrite(E1, value); //PWM调速
analogWrite(E2, value); //PWM调速
delay(30);
}
delay(1000);}
}
Hope this can help you.
Best regards
