Auch hier werde ich durch die Lektüre der niederländischen Kollegen nicht schlauer, sondern eher dümmer.

7 color flashing LED module automatically uses 5mm round high-brightness light-emitting diode which has the following characteristics: Specifications

/ *
Blink
Turns on an LED on for two second, then off for two second, repeatedly.
This example code is in the public domain.
* /
void setup () {
/ / Initialize the digital pin as an output.
/ / Pin 13 has an LED connected on most Arduino boards:
pinMode (13, OUTPUT);
}
void loop () {
digitalWrite (13, HIGH); / / set the LED on
delay (2000); / / wait for a second
digitalWrite (13, LOW); / / set the LED off
delay (2000); / / wait for a second
}
