This is a sample code to get students started on their EL wiring project known as EL Wiro. This is for the Maker Robotics course at International School Manila.

Basic Code for EL Wiro

// Test sketch for El Escudo Dos
// Turn each EL channel (A-H) on in sequence and repeat
// Mike Grusin, SparkFun Electronics

  int A = 2;
  int B = 3; 
  int C = 4;
  int D = 5;
  int E = 6;
  int F = 7; 
  int G = 8;
  int H = 9;

void setup() {                
  // The EL channels are on pins 2 through 9
  // Initialize the pins as outputs
  pinMode(2, OUTPUT);  // channel A  
  pinMode(3, OUTPUT);  // channel B   
  pinMode(4, OUTPUT);  // channel C
  pinMode(5, OUTPUT);  // channel D    
  pinMode(6, OUTPUT);  // channel E
  pinMode(7, OUTPUT);  // channel F
  pinMode(8, OUTPUT);  // channel G
  pinMode(9, OUTPUT);  // channel H
  // We also have two status LEDs, pin 10 on the Escudo, 
  // and pin 13 on the Arduino itself 
}

void loop() 
{
  digitalWrite(A, HIGH);
  delay(500);
    digitalWrite(A, LOW);
