Hey guys,
I am new to using Arduino and I have a code for a stepper motor. I have modified the same code in three different ways.
So the first code allows the motor to turn forward and back constantly, the second code has a 1 sec delay between the movements and the third code has a 5 second delay.
I want to set up a code where I input a number into the serial monitor e.g, 1 and it outputs the first code which is the motor running constantly, then if I input 2 it will run the code with the 1 second interval and so on....
This is the code I am using for the stepper motor at the moment, is anyone able to help me out?
Thanks!! 
int Distance = 0; // Record the number of steps we've taken void setup() {
void setup() {
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
digitalWrite(3, LOW);
digitalWrite(4, LOW);
}
void loop() {
digitalWrite(4, HIGH);
delayMicroseconds(1000);
digitalWrite(4, LOW);
delayMicroseconds(1000);
Distance = Distance + 4; // record this step // Check to see if we are at the end of our move
// two rotation for 1/8 bridge and 1 rotation for 1/6 bridge (for this code)
if (Distance == 3500) { // We are! Reverse direction (invert DIR signal)
if (digitalRead(3) == LOW) {
digitalWrite(3, HIGH); }
else {
digitalWrite(3, LOW);
} // Reset our distance back to zero since we're // starting a new move
Distance = 0; // Now pause for half a second delay(500);
}
}
