USB Addressable LED string controller
with full brightness control
For WS2811-based addressable LEDs
LED channels with 256 brightness levels for full RGB color mixing
be used with single-color or RGB LED strings (RGB use 3 channels)
- Supports WS2811 high-speed version protocol.

connected to the red and blue wires
When you power on the PC, the board will immediately run a script which
is pre-loaded in flash. If you have overwritten this with your own
script, this will run. The pre-loaded script causes all LEDs to
sequence in a fade up/down “wave” from 1 to 60 (ie 1-20 if
Scripts are repeated continuously.
When a command is sent by the PC via USB, the script stops running and
the command is processed. The script is then not run again until the
This app is used for the
- Testing LEDs and connections
by turning LEDs on/off or setting to a specified brightness.
- Creating simple
“attract mode” scripts and storing in the on-board
- Assigning an ID to board,
when using more than one board
When clicked, all subsequent commands will be stored in on-board flash.
Next time the board is powered on, the script will run and loop forever
until a command is sent from the host via USB.
Clicking “Stop Recording” will end the script
This will cause any stored script to be deleted, so on next power-on,
nothing will happen until the host sends commands via USB.
This adjusts the time taken to perform a fade. A fade occurs whenever
the state of a LED changes, ie its brightness is changed or switched
off/on. This setting affects all subsequent state changes. This can be
stored in scripts.
Script Step Delay
This adjusts the time interval when scripts are being executed. This
can be stored in a script. This is not relevant when sending direct
commands from the host.
On this screen, the brightness of any of the 60 LEDs can be set. The
command is executed immediately by the board, and if you are storing a
script, is also added to the script.
On the latest version (requires latest firmware) the LED(s) can also be
set to flash at one of 3 rates on this screen.
On this screen, a group of 8 LEDs is set to a pattern. The LEDs are
either fully off or fully on. There are 8 groups of 8 LEDs. Also, all
LEDs can be set to a random pattern.
The command is executed immediately by the board, and if you are
storing a script, is also added to the script.
the LEDBlinky application
This is a third-party application available in free or paid versions.
It is actually a suite of programs enabling configurations to be
stored, animations to be created, and has special MAME features.
that LEDBlinky supports direct control of the board via USB only. It
does not support creation of scripts for storing on the board.
Version 5.0 required.
- With RGB LEDs, you can
specify colors for individual controls or
using a pre-defined colors.ini file. Colors or intensities can also be
customized on a game-by-game basis.
- Use audio output (music or
game sounds) to blink, fade, or
LEDs – great for use with Jukebox software.

- Flash start buttons when

directly linked to a Device/Port.
- Extensive audio animation
options let you completely customize
the LEDs blink to music or game sounds.

LEDBlinky can play a LED animation

- While playing a game,
LEDBlinky can play a continuous LED

to animate the LEDs. The LED animation will only effect unused controls.

LEDs from your own
An SDK is available which includes a DLL to provide an API to enable
LED control in your programs. The SDK includes the DLL, plus example
source code showing its use. A test program for checking operation of
the DLL is also included.
