How the System Works

The rotating display uses a 28BYJ-48 stepper motor controlled by an Arduino through direct GPIO pin manipulation. The system features:

• Precise stepper motor control without additional libraries
• Adjustable rotation speed through delay timing
• Power-saving design that cuts power when not rotating
• Simple, efficient code that's easy to modify
• Compact design using minimal components

Circuit Diagram

The circuit connects the Arduino Nano directly to the stepper motor through the ULN2003 driver. The motor requires separate 12V power while the Arduino can be powered via USB or the same power supply through its voltage regulator.

Arduino Code

int delaytime = 2;

int port[4] = {12, 11, 10, 9};

// sequence of stepper motor
int seq[8][4] = {
  {  LOW, HIGH, HIGH,  LOW},
  {  LOW,  LOW, HIGH,  LOW},
  {  LOW,  LOW, HIGH, HIGH},
  {  LOW,  LOW,  LOW, HIGH},
  { HIGH,  LOW,  LOW, HIGH},
  { HIGH,  LOW,  LOW,  LOW},
  { HIGH, HIGH,  LOW,  LOW},
  {  LOW, HIGH,  LOW,  LOW}
};

void rotate(int step) {
  static int phase = 0;
  int i, j;
  int delta = (step > 0) ? 1 : 7;

  step = (step > 0) ? step : -step;
  for(j = 0; j < step; j++) {
    phase = (phase + delta) % 8;
    for(i = 0; i < 4; i++) {
      digitalWrite(port[i], seq[phase][i]);
    }
    delay(delaytime);
  }
  // power cut
  for(i = 0; i < 4; i++) {
    digitalWrite(port[i], LOW);
  }
}

void setup() {
  pinMode(port[0], OUTPUT);
  pinMode(port[1], OUTPUT);
  pinMode(port[2], OUTPUT);
  pinMode(port[3], OUTPUT);
}

void loop() {
  rotate(100);
}

Code Explanation:

Setup:

Configures the Arduino pins as outputs to control the stepper motor through the ULN2003 driver.

Loop:

Continuously rotates the motor 100 steps at a time. The rotation direction and speed can be easily adjusted by modifying the step value and delay time.
