RANGMANG Dance Mode Configuration

This configuration defines how the RANGMANG module controls LED dance modes. Each row encodes the following parameters (ADRGBSEM format):

A (Address) – 2 digits (A01–A98 for module, A99 for all).
D (Mode) – D01–D38 for dance styles, D99 for random dance selection.
R / G / B – 3 digits each. Normal range R000–R250, G000–G250, B000–B250. Special values:
- R251–R255 → Random Red
- G251–G255 → Random Green
- B251–B255 → Random Blue
S (Dance Time 1) – 3 digits, milliseconds per pixel move (first timing), range S000–S999.
E (Dance Time 2) – 3 digits, milliseconds per pixel move (second timing), range E000–E999.
M (Pixel Count) – 3 digits, number of dancing pixels. - ATmega328: M001–M480 - ATmega128: M001–M999

A (Channel)	D (Mode)	R (Red)	G (Green)	B (Blue)	S (Dance Time 1)	E (Dance Time 2)	M (Pixel Count)
A01	D12	R251	G251	B251	S001	E001	M128

RANGMANG Fixed Color Mode Configuration (ATmega128 – 999 Pixels)

A (Address) – 2 digits (A01–A98 for module, A99 for all).
D (Mode) – must always be D00 for solid color.
R / G / B – 3 digits each, range R000–R255, G000–G255, B000–B255.
S (Start Pixel) – 3 digits, range S000–S999.
E (End Pixel) – 3 digits, range E000–E999.
M (Memory Slot) – 3 digits, M000 without save, M001–M999 for slots.

A (Channel)	D (Mode)	R (Red)	G (Green)	B (Blue)	S (Start Pixel)	E (End Pixel)	M (Memory Slot)
A01	D00	R200	G050	B100	S001	E120	M010

Power Regulation Notes

For 5V LED strips: You can remove the regulator and directly power the microcontroller from the strip's 5V socket.
For 12V LED strips: You must use a 12V-to-5V regulator to power the microcontroller safely.
Note: To prevent reverse connection of the LED strip to the module, use a properly keyed connector. If necessary, add a diode in series with the microcontroller's power input to protect against polarity reversal.

In this version, the microcontroller is ATmega328P with the same specifications, but with support for 480 pixels

✅ Module Addressing Instructions



To address a module, simply follow the method below.
For example:

Address 2 → CH=02

Address 34 → CH=34

After sending the command, the module will respond and operate according to the specified address.

Please note:

Valid addresses range from 01 to 98.

Address 99 is a shared address that applies to all modules.

Therefore, each module will respond and act to its assigned address (between 01 and 98) as well as to the shared address 99
