EL wire is flexible plastic cord that glows brightly when high-voltage AC is applied to it. It’s available in numerous colors with cool, and requires very little current, but it can be difficult to work with because of the high-voltage requirements. The Elecrow EL Shield enables you to implement up to 8 channels of EL wires or tapes in to your project and gives you solution to control the EL wires. With Arduino or Crowduino, You will be able to control 8 EL devices simultaneously and separately. The controlling method is as simple as controlling an LED. Driven by PWM, it can create a colorful and florid effect by controlling each EL wire according to your own programs.
