Dual LED Chaser Arduino Project Circuit for Beginners

Introduction

In This Project, we are going to make a Dual LED Chaser Arduino Circuit Project for Beginners. Basically, The Dual LED Chaser Arduino Project is an exciting electronics project that involves creating a circuit that flashes 12 LEDs in a chaser pattern. This project is an excellent way for beginners to learn about Arduino programming, electronics, and circuit design.

The circuit consists of an Arduino board, 12 LEDs, and 12 resistors with values between 220 ohms and 470 ohms. The LEDs are arranged in two rows, with each row containing six LEDs. The LEDs flash alternately, creating a dual-chaser effect.

Working Explanations

The circuit uses an Arduino board to control the flashing of the LEDs. The board is programmed to output a signal to the LEDs in a specific pattern, creating the chaser effect. Each LED is connected in series with a resistor, which limits the current flowing through the LED and protects it from damage.

The Arduino board sends signals to each LED in turn, turning it on and off in a specific sequence. The LEDs are arranged in two rows, with each row containing six LEDs. The first LED in each row is turned on, followed by the second, third, and so on until all six LEDs in the row are turned on. Then, the first LED in the second row is turned on, followed by the second, third, and so on, until all six LEDs in the second row are turned on. The process then repeats, creating the dual chaser effect.

  for (int i = 2; i <= 13; i++) {
    pinMode(i, OUTPUT);
  }
}
uint16_t chase2 = 13; // keeps track of second LED movement

void loop() {
  // move first LED from left to right and second from right to left
  for (int i = 2; i < 13; i++) {
    allLEDsOff();
    digitalWrite(i, HIGH);      // chaser 1
    digitalWrite(chase2, HIGH); // chaser 2
    chase2--;
    // stop LEDs from appearing to stand still in the middle
    if (chase2 != 7) {
      delay(SPEED_MS);
    }
  }
  // move first LED from right to left and second LED from left to right
  for (int i = 13; i > 2; i--) {
    allLEDsOff();
    digitalWrite(i, HIGH);      // chaser 1
    digitalWrite(chase2, HIGH); // chaser 2
    chase2++;
    // stop LEDs from appearing to stand still in the middle
    if (chase2 != 8) {
      delay(SPEED_MS);
    }
  }
}
// function to switch all LEDs off
void allLEDsOff(void)
{
  for (int i = 2; i <= 13; i++) {
    digitalWrite(i, LOW);
  }
}
