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–D55 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.

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–M099 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

If the module is used individually, connect the Bluetooth power jumper.

If the modules are used in parallel, only connect the jumper for the module linked to Bluetooth and disconnect the rest.

Install a 5V regulator for 12V LED strips; for 5V LED strips, no regulator is needed.

Use a single wire to solder and connect the input and output pins of the regulator directly on the board.

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.

✅ Module Addressing Instructions


To address a module, simply follow the method below.

For example:

Old address 1   New Address 2  →  CH01=02
Old address 23  New Address 47 →  CH23=47

Important:
After programming, all modules have an initial default address of 01.
Therefore, during the first addressing, the old (current) address is always 01.

Addressing format:


CH  old address  =  new address

For example:
CH01=03

After changing the address, the module will respond using its new address.
For example, if the new address is 03, the module will reply to:
New Address=03

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.

In each microcontroller’s folder, the software directory “dude 6.4” is available. Using the file “Program Chip.bat,” you simply need to connect the USBasp to the microcontroller and then click on “Program Chip.bat” to program the microcontroller.

If you need the module as a single unit, you can use regular sockets. However, when using multiple modules in parallel, only the Bluetooth socket should be connected through long-pin headers so that the remaining modules can receive Bluetooth serial data. Next, it is better to mechanically connect the modules together using spacer screws. For the final module, you can insulate the pins or use a suitable cover. Alternatively, if you are certain that you will not expand the number of modules in the future, you may use short-pin headers instead.

When using long RGB strips, make sure to pay attention to the voltage of the microcontroller and Bluetooth. Using an unsuitable regulator or a power supply with insufficient current capacity can cause severe voltage drops, which may lead to the Bluetooth and microcontroller shutting down
