==== Elecfreaks Starter Kit ====

{{:helvepic32:elecfreakskit:elecfreakskit-p1-01.png?800|}}

Der [[http://shop.boxtec.ch/elecfreaks-arduino-starter-kit-absolute-beginner-p-42444.html|Elecfreaks Starterkit]] bietet eine leichten Einstieg in die Welt des Arduino. 

Hier kann man auch sehen, wie einfach es ist, diese Module mit dem HelvePic32 zu betreiben. 

Im Nachfolgenden sind die Beschreibungen als Arbeitskarten für den Arduino als auch den HelvePic32 dargestellt.

Beim HelvePic haben wir den GVSled-Wing verwendet.

Der Code kann [[http://www.mathias-wilhelm.de/arduino/assets/downloads/Elecfreaks.zip|hier herunter geladen]] werden, sowie die [[http://www.mathias-wilhelm.de/arduino/assets/downloads/HelvePic32.zip|HelvePic32 Bibliothek]].

<code c>/*
  part1  ARDUINO START
  Turns on an LED on for one second, then off for one second, repeatedly.

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
#if defined(__AVR__)
int led = 13;
#elif defined(__PIC32MX__)
#include 
int led = nP[LEFT][2];
#endif

// the setup routine runs once when you press reset:
void setup() {
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);               // wait for a second
