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, runs cool, and requires very little current, but can be difficult to work with because of the high voltage requirements. EL Escudo Dos contains circuitry to switch high-voltage AC on and off safely, allowing you to create animated displays or whatever else your imagination can come up with.
In addition to this shield, you will need Arduino headers (see the related products below), an inverter (a component that generates the high-voltage AC needed by EL wire), and the EL wire itself. You can use an externally powered inverter or the shield can supply power to your inverter through the Arduino. Its built-in regulator comes preset to 3.3V, but can be set to any voltage by changing two resistors, or can be bypassed with a solder jumper to send the Arduino's raw voltage directly to the inverter (perfect for 12V setups).
Arduino Electroluminescence Shield Features
- Eight opto-isolated, zero-crossing control channels
- No library needed; control is as easy as turning an 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; you must solder headers to the shield before you can plug it into your Arduino board
Power and EL Connections EL Escudo Dos has both 0.1"-pitch through-hole pads and 2mm two-pin male JST connectors for connection to/from your inverter and to your electroluminescent materials. Your power inverter should connect to AC from Inverter. For an externally powered inverter (e.g. 12V for large projects), that is the only power connection used. DC to Inverter is for supplying power from the Arduino to your inverter, which by design is for small projects using a 3.3V inverter which can run only a few meters of EL wire. With modifications, it can be possible use DC to Inverter to power a beefier inverter through the Arduino.
