Working Explanations

The Moving Light Display Arduino Project uses an Arduino board to control the display of four LEDs. The board is programmed to output a signal to the LEDs in a specific pattern, creating the moving light display.

The LEDs are connected to the Arduino board through four resistors with values between 220 and 470 ohms. The resistors are used to limit the current flow to the LEDs, protecting them from damage.

When the Arduino board is powered on, it begins to output a signal to the first LED, which turns on. The board then outputs a signal to the second LED, which turns on while the first LED turns off. This process continues for all four LEDs, creating the moving light display.

    // check if bit in pattern is set or not and switch LED accordingly
    if (pattern[pattern_num] & mask) {
      digitalWrite(i, HIGH);
    }
    else {
      digitalWrite(i, LOW);
    }
    mask <<= 1;   // adjust mask for checking next bit in pattern
  }
  pattern_num++;  // move to next pattern for next function call
  // keep pattern within limits of pattern array

    pattern_num = 0;
  }
}

Applications

The Moving Light Display Arduino Project has several practical applications. It can be used as a decorative light display, such as for a holiday decoration or party decoration. It can also be used as an indicator, such as to indicate the status of a device or system.

The project can also be expanded by adding more LEDs and programming the board to control them in a more complex pattern, creating a more intricate light display. Additionally, the circuit can be modified and expanded to control other electronic devices, such as motors, servos, or sensors, making it a versatile tool for electronics enthusiasts.
