El Escudo Dos

The new version adds 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).

EL Escudo Dos is an Arduino shield 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 Escudo Dos contains circuitry to safely switch high-voltage AC on and off, allowing you to create animated displays or whatever else your imagination can come up with.

Features:

• Eight opto-isolated, zero-crossing control channels
• No library needed - control is as easy as turning a LED on and off
• Shield is compatible with 5V or 3.3V Arduinos
• 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
• External inverter required, not included
• Comes without headers, soldering required

Important:

• to start using it you need to have inverter and El Wire (sold separatly)
• shield uses digital pins D2-D9 for channel control
