Quelltext der Seite Evaluate an analog value through the ADC on the Arduino Nano

Yes, and because I like it small, there's the Arduino Nano. I did roughly the same again based on the Nano. In this case I connected the input from the Poti with the delay of the LED LOW. I can now regulate the blinking frequency. Here's a picture of the setup on my breadboard:

 int potiPin = 0;
 int potiVal = 0;
 int ledPin = 2;
 
 void setup() {
   int potiPin = 0;
   pinMode(ledPin, OUTPUT);
 }
 
 void loop() {
   int potiVal = analogRead(potiPin);
   digitalWrite(ledPin, HIGH);
   delay(100);
   digitalWrite(ledPin, LOW);
   delay(potiVal*2);
 }
