BD-1 Logic Panel Manual and Description

1. Overview

This sketch is designed for a BD-1 Droid Logic Panel, powered by an Arduino Pro Mini 5V and using the BD1 Board.
The sketch allows for extensive control over the LED display, including color modes, brightness levels, fade effects, and EEPROM-based settings storage.

• LEDs: 251 WS2812B RGB LEDs
• Serial Baud Rate: 9600

2. Features

EEPROM Support: Saves configuration settings to EEPROM, allowing settings to persist across resets.

Color Modes: 14 predefined colors, including a random color mode and a multicolor mode for varied displays.

Brightness Control: Adjustable minimum and maximum brightness levels, with options for a uniform brightness or random brightness per LED.

Fade Effect: Configurable fade effect for smooth transitions between colors.

3. Configurable Variables:

Color Mode:

• Variable: colorMode
• Command: color [mode]
• Description: Changes the color mode. Available modes are:
  • blue
  • red
  • yellow
  • green
  • purple
  • pink
  • multicolor
  • random (picks a random single color for all LEDs)
  • cyan
  • orange
  • lime
  • magenta
  • white

Blink Speed:

• Variable: blinkSpeed
• Command: blinkSpeed [milliseconds]
• Description: Sets the blink speed (delay between updates) in milliseconds.
• Range: Any integer value representing milliseconds.

Fade Effect:

• Variable: enableFade
• Command: fade [on/off]
• Description: Enables or disables the fading effect for transitions between color changes.

Same Brightness for All LEDs:

• Variable: sameBrightness
• Command: sameBrightness [on/off]
• Description: When enabled, all LEDs have the same brightness. When disabled, each LED can have a different brightness.

Minimum Brightness:

• Variable: minBrightness
• Command: minBrightness [value]
• Description: Sets the minimum brightness level for LEDs.
• Range: 0-255

Maximum Brightness:

• Variable: maxBrightness
• Command: maxBrightness [value]
• Description: Sets the maximum brightness level for LEDs.
• Range: 0-255

1. LED On/Off State:

• Variable: isOn
• Command: on or off
• Description: Turns the LEDs on or off.

EEPROM Storage Variables:

These settings are saved to EEPROM and can be loaded or saved:

• colorMode
• blinkSpeed
• enableFade
• sameBrightness
• minBrightness
• maxBrightness
• isOn

Non-Configurable Variables:

• NUM_LEDS: Defines the number of LEDs in the strip (constant).
• DEFAULT_BRIGHTNESS: Sets the default brightness level when sameBrightness is enabled.

4. Via sketch configurable Variables:

1. LED Configuration:
   • LED_PIN: The pin connected to the BD-1 Board. Default is set to 10.
   • NUM_LEDS: Total number of LEDs in the strip. This is set to 251 but can be adjusted if you have a different number.
   • MAX_ACTIVE_LEDS: Sets the maximum number of LEDs that can light up at the same time. Default is 75.
   • MIN_ACTIVE_LEDS: Sets the minimum number of LEDs that should light up at the same time. Default is 10.
   • DEFAULT_BRIGHTNESS: Sets the default brightness level if sameBrightness is enabled. Default is 128 (range: 0–255).

5. Serial commands:

Here is the list of serial commands that can be used in your sketch:

Available Commands:

Change Color Mode:

• Command: color [mode]
• Example: color red
• Description: Changes the color mode. Available modes:
  • blue
  • red

  • multicolor
  • random (picks a random single color for all LEDs)
  • cyan
  • orange
  • lime
  • magenta
  • white

Set Blink Speed:

• Command: blinkSpeed [milliseconds]
• Example: blinkSpeed 500
• Description: Sets the blink speed in milliseconds (delay between updates).

Toggle Fade Effect:

• Command: fade [on/off]
• Example: fade on
• Description: Enables or disables the fade effect between color transitions.

Toggle Same Brightness for All LEDs:

• Command: sameBrightness [on/off]
• Example: sameBrightness on
• Description: When enabled, all LEDs have the same brightness. When disabled, each LED can have a different (random) brightness.

Set Minimum Brightness:

Turn LEDs On:

• Command: on
• Description: Turns on the LEDs.

Turn LEDs Off:

• Command: off
• Description: Turns off the LEDs and clears the strip.

Save Settings to EEPROM:

• Command: save
• Description: Saves the current configuration (color mode, brightness, etc.) to EEPROM.

1. Clear EEPROM:
   • Command: clear
   • Description: Clears all stored data in the EEPROM.
2. Check Current Status:
   • Command: status
   • Description: Prints the current settings including color mode, brightness levels, fade status, and on/off status.

Send commands in lowercase without additional formatting.

6. Example Usage
