Programmability Depth
Four Dimensions of Programmability
An LED lanyard can be programmed across four independent dimensions. Each dimension adds a layer of customization depth — from simple out-of-box patterns to fully custom firmware behavior.

Light Patterns
Every lanyard ships with 4 built-in flash modes: Slow Flash (1 Hz gentle pulse), Fast Flash (3 Hz rapid blink), Strobe (10 Hz intense burst), and Fade (smooth RGB color transition). These are stored in the microcontroller's firmware and activated by tapping the push button.
Beyond the built-in modes, the firmware supports custom pattern programming. A custom pattern is a sequence of color + brightness + duration steps stored in the chip's memory. For example: blue 100% for 2s → fade to white over 1.5s → white strobe at 8 Hz for 3s → off for 1s → repeat. Because the pattern is stored in non-volatile memory, it is not lost when the battery runs out — after installing fresh batteries, the same custom pattern runs without needing to be reprogrammed.

Control Triggers
What tells the lanyard to change its behavior? The programmable trigger system supports four input sources: the built-in push button (tap/hold sequences), RF remote signal (GFC004, 433MHz, 250m range), DMX512 command (GFC005, from any lighting console), and APP command (GFC008, via Bluetooth or internet).
Each trigger can be mapped to a different response. For example: push button cycles through 7 colors, RF remote triggers a crowd-wide strobe, DMX console runs a 16-step chase sequence, and APP lets the wearer pick a custom color from a palette. Because the trigger mapping is programmable, the same lanyard can behave differently depending on which transmitter is active.

Timing & Sync
Programmable timing controls three aspects: pattern speed (adjustable from 0.5 Hz to 20 Hz), synchronization (all lanyards receive the same RF or DMX command within <5ms), and schedule (timed sequences that run for a set duration then stop). For DMX-controlled shows, the lighting programmer sets the timing in the console; the lanyards follow the show file.
For standalone custom patterns, the timing is defined in firmware — duration per step, transition curve (instant, linear fade, or S-curve), and loop behavior. Because the microcontroller runs from an internal oscillator, timing is consistent across all units in a batch. No calibration needed between lanyards.

Brand Integration
The programmable layer extends to the visual identity of the lanyard itself. The badge can be laser-cut into any brand logo shape, with LEDs positioned to highlight specific features of the silhouette. The strap supports full-color sublimation printing for photographic brand artwork. The APP (if ordered) is white-labeled with your brand colors, logo, and name.
On the firmware side, brand-specific color palettes can be programmed — replacing the default 7-color cycle with a sequence of your brand colors only. This means the lanyard cycles through your corporate palette, not a generic rainbow. Because the palette is stored in firmware, it cannot be overridden by user button presses — the brand identity stays locked.
