A VPN is an essential component of IT security, whether you’re just starting a business or are already up and running. Most business interactions and transactions happen online and VPN

Continuing our saga from Part 1, We finished soldering up the controller shield with all the components. We have downloaded the library, and have connected the stepper motor. The motor has 4 wires, which we have attached to the M1/M2 connector. The wires connect top to bottom:

1. Orange
2. Yellow
3. N/C
4. Green
5. Brown

A 12v power supply connects to the motor external power connector. Make sure you do not enable the Arduino power jumper just to the right of the motor external power connector.

Code:

#include <AFMotor.h>

AF_Stepper motor(48, 1);

void setup() {

motor.setSpeed(10); // 10 rpm

motor.step(100, FORWARD, SINGLE);
motor.release();
delay(1000);
}

void loop() {
motor.step(100, FORWARD, SINGLE);
motor.step(100, BACKWARD, SINGLE);

motor.step(100, FORWARD, DOUBLE);
motor.step(100, BACKWARD, DOUBLE);

motor.step(100, FORWARD, INTERLEAVE);
motor.step(100, BACKWARD, INTERLEAVE);

motor.step(100, FORWARD, MICROSTEP);
motor.step(100, BACKWARD, MICROSTEP);
}
