Grove - EL Driver

Grove - EL Driver is designed for driving EL Wires. It integrates a very small inverter to drive the EL Wire, so you can easily light up the EL Wire with just one single Grove cable.

Version Tracker

v1.0Initial public releaseDec 11, 2014

Supported EL Wires:


  • Grove compatible interface
  • 3.3V/5V Compatible
  • Integrated Inverter Transformer
  • Input Current: 300mA Max (According to the load)
  • Supported max EL Capacitance: 15nF
More details about Grove modules please refer to [Grove System](


Play with Arduino

Here we show how to use Arduino to control the state of the LED.

  1. Connect the Grove - EL Driver to Base Shield's digital port 2 with 4pin Grove Cable. Of course you can change to other valid digital ports if it's necessary and the definitions of the port should be changed too. Connect a EL Wire to EL Driver J1 port with the given cable in product package.

  2. Plug it onto the Arduino/Seeeduino. Connect the board to PC using USB cable.

  3. Copy the demo code to your sketch, then upload to Arudino or Seeeduino board. You will see the EL Wire blink every second.

#define ELPin 2 //connect EL Driver to digital pin2
void setup() {
// initialize the digital pin2 as an output.
pinMode(ELPin, OUTPUT);
void loop() {
digitalWrite(ELPin, HIGH); // set the EL Wire on
delay(500); // for 500ms
digitalWrite(ELPin, LOW); // set the EL Wire off

Play with Codecraft


Step 1. Connect Grove - EL Driver to port D2 in a Base Shield

Step 2. Plug the Base Shield to your Seeeduino/Arduino.

Step 3. Link Seeeduino/Arduino to your PC via an USB cable.


Step 1. Open Codecraft, add Arduino support, and drag a main procedure to working area.

If this is your first time using Codecraft, see also [Guide for Codecraft using Arduino](

Step 2. Drag blocks as picture below or open the cdc file which can be downloaded at the end of this page.

Upload the program to your Arduino/Seeeduino.

When the code finishes uploaded, you will see the EL blinking.
