Python + Arduino on/off the LED.

#define LED 13

// Using http://slides.justen.eng.br/python-e-arduino as refference

void setup() {
    pinMode(LED, OUTPUT);
    Serial.begin(9600);

void loop() {
    if (Serial.available()) {
        char serialListener = Serial.read();

Thanks so much! This git got me unstuck in my project.

It leave me this error:

any idea?

It was a problem with the identation in the code, sorry.
