產品名稱：Sparkfun原廠 EL Sequencer 控制器(COM-12781)
產品介紹：
EL Sequencer 控制器是一組以ATmega為核心的控制板，能夠讓使用者能夠對EL作連續的控制。
如果您已有一組Arduino USB板，使用EL擴充版會更適合你。

影片中使用8組長度12''的EL冷光線
EL冷光線必須使用高壓交流電源_125V_425Hz 。雖然冷光線所需電力相當小，但是我們是無法使用一般的transistors來控制開啟/關閉。因此，Sparkfun製作了EL擴充板(for Arduino)/ EL Sequencer控制器(for一般MCU)，使用TRIACs 控制多達8組EL。
其他應用，歡迎參考 Heartbeat Straight Jacket 的相關文件，他結合EL冷光線以及無線控制。

原官方說明：
Description: The SparkFun EL Sequencer is a board that contains an Arduino-compatible microcontroller, and circuitry for controlling up to eight strands of electroluminescent wire. EL wire is flexible plastic cord that glows brightly when high-voltage AC is applied to it. It’s available in numerous colors (see the related products below), runs cool, and requires very little current, but can be difficult to work with because of the high-voltage requirements. The EL Sequencer can safely switch high-voltage AC on and off, allowing you to easily create animated displays or whatever else your imagination can come up with.
In addition to this board, you will need an inverter (a component that generates the high-voltage AC needed by EL wire), EL wire/tape/panels, and a 5V FTDI BOB or cable to load your own programs. The board also has headers for XBee and NRF24L01+ radio modules for wireless projects. SparkFun carries two inverters, a 3V-input version that can drive a few feet of EL wire, and a 12V-input version capable of driving dozens of feet of EL wire. Choose the one appropriate to your power source and driving requirements. The EL Sequencer possesses zero-crossing optoisolated triacs for noise-free operation and full isolation between the AC and DC sides, and includes a 1.5A adjustable linear regulator to supply regulated DC to an external inverter (not included).
Nate has used EL wire to make amazing interactive costumes; check out his Heartbeat Straitjacket and demo video.
Note: We have fixed the silkscreen error on this board; the FTDI “black” and “green” labels have been fixed.
Features:
- ATmega 328p running at 8MHz, with Arduino bootloader
- Eight opto-isolated, zero-crossing EL control channels
- Headers for XBee and NRF24L01+ for optional wireless control
- No library needed - control is as easy as turning a LED on and off
- Integrated 1.5A linear regulator (LM317) to supply regulated DC power to external inverter
- Linear regulator preset to 3.3V, but can be changed via PTH resistors, or bypassed entirely
- Can be powered by a 3.7V Lipo battery (using 3V inverter), or an external 3.3V to 16V supply (using 3V or 12V inverter)
- 5V FTDI BOB or cable required for reprogramming, not included
- External EL inverter required, not included
