Module onBoard

The RGB-LED is built on the MCU S2! You don't have to connect anything else here.

Programming (Arduino)​

This sketch lets the RGB-LED light up in a random color every second.

#include <Adafruit_NeoPixel.h>
Adafruit_NeoPixel rgb_led_1

void setup() {
    rgb_led_1.begin();
    rgb_led_1.setBrightness(30);
}

void loop() {
  if (time_startInterval > time_actualInterval + intervalInterval)
    {
        time_actualInterval = millis();
        rgb_led_1.setPixelColor(0,rgb_led_1.Color(random(0, 255), random(0, 255), random(0, 255)));
        rgb_led_1.show();
    }
}

Programming (Blockly)​

In Blockly, the sensor can be read using the following block:
