Hello, i was trying to find some information through the internet but i was unsuccessful. I am wondering is there any way to add switches to 3 stepper motors hooked up thru and arduino using easy driver? i would like to create a switch that would be able to start or stop each of the three motors im trying to connect, if there is a better way for this to be accomplished i would greatly appreciate any suggestions

this is the simple code i am basing it off of.

Code: [Select]
#define DIR1_PIN 4
#define STEP1_PIN 5
#define DIR2_PIN 6
#define STEP2_PIN 7
#define DIR3_PIN 8
#define STEP3_PIN 9
#define DELAY 150


void setup() {
Serial.begin(9600);
pinMode(DIR1_PIN,OUTPUT);
pinMode(STEP1_PIN,OUTPUT);
pinMode(DIR2_PIN,OUTPUT);
pinMode(STEP2_PIN,OUTPUT);
pinMode(DIR3_PIN,OUTPUT);
pinMode(STEP3_PIN,OUTPUT);
}


void loop() {
int i;

digitalWrite(DIR1_PIN, LOW); // Set the direction.
digitalWrite(DIR2_PIN, LOW); // Set the direction.
digitalWrite(DIR3_PIN, LOW); // Set the direction.
delay(DELAY);
Serial.println(">>");

for (i = 0; i<6800; i++) // Iterate for 4000 microsteps.
{
digitalWrite(STEP1_PIN, LOW); // This LOW to HIGH change is what creates the
digitalWrite(STEP1_PIN, HIGH); // "Rising Edge" so the easydriver knows to when to step.
if((i%2)==0) {
digitalWrite(STEP2_PIN, LOW); // This LOW to HIGH change is what creates the
digitalWrite(STEP2_PIN, HIGH); // "Rising Edge" so the easydriver knows to when to step.
}
if((i%4)==0) {
digitalWrite(STEP3_PIN, LOW); // This LOW to HIGH change is what creates the
digitalWrite(STEP3_PIN, HIGH); // "Rising Edge" so the easydriver knows to when to step.
}
delayMicroseconds(DELAY); // This delay time is close to top speed for this
} // particular motor. Any faster the motor stalls.

digitalWrite(DIR1_PIN, HIGH); // Change direction.
digitalWrite(DIR2_PIN, HIGH); // Change direction.
digitalWrite(DIR3_PIN, HIGH); // Change direction.
delay(DELAY);
Serial.println("<<");

for (i = 0; i<6800; i++) // Iterate for 4000 microsteps
{
digitalWrite(STEP1_PIN, LOW); // This LOW to HIGH change is what creates the
digitalWrite(STEP1_PIN, HIGH); // "Rising Edge" so the easydriver knows to when to step.
if((i%2)==0) {
digitalWrite(STEP2_PIN, LOW); // This LOW to HIGH change is what creates the
digitalWrite(STEP2_PIN, HIGH); // "Rising Edge" so the easydriver knows to when to step.
}
if((i%4)==0) {
digitalWrite(STEP3_PIN, LOW); // This LOW to HIGH change is what creates the
digitalWrite(STEP3_PIN, HIGH); // "Rising Edge" so the easydriver knows to when to step.
}
delayMicroseconds(DELAY); // This delay time is close to top speed for this
} // particular motor. Any faster the motor stalls.

would i be able to do something similar to this with three easy drivers already connected to an arduino ??
