Пины и сигналы

analogPin = 3; // potentiometer connected to analog pin 3
int val = 0; // variable to store the read value
void setup() {
pinMode(13, OUTPUT); // sets the digital pin 13 as output
pinMode(ledPin, OUTPUT); // sets the pin as output
}
void loop() {
digitalWrite(13, HIGH); // sets the digital pin 13 on
delay(1000); // waits for a second
digitalWrite(13, LOW); // sets the digital pin 13 off
delay(1000); // waits for a second
val = analogRead(analogPin); // read the input pin
analogWrite(ledPin, val / 4); // analogRead values go from 0 to 1023, analogWrite values from 0 to 255
