Principe de Fonctionnement

/*
Analog input, analog output, serial output

Reads an analog input pin, maps the result to a range from 0 to 255
and uses the result to set the pulsewidth modulation (PWM) of an output pin.
Also prints the results to the serial monitor.

The circuit:
* potentiometer connected to analog pin 0.
Center pin of the potentiometer goes to the analog pin.
side pins of the potentiometer go to +5V and ground
* LED connected from digital pin 9 to ground

// These constants won’t change. They’re used to give names
// to the pins used:
const int analogInPin = A0; // Analog input pin that the potentiometer is attached to
const int analogOutPin = 9; // Analog output pin that the LED is attached to

int sensorValue = 0; // value read from the pot
int outputValue = 0; // value output to the PWM (analog out)

void setup() {
// initialize serial communications at 9600 bps:
Serial.begin(9600);
}

void loop() {
// read the analog in value:
sensorValue = analogRead(analogInPin);
// map it to the range of the analog out:
outputValue = map(sensorValue, 0, 1023, 0, 255);
// change the analog out value:
analogWrite(analogOutPin, outputValue);
if (sensorValue < 260){
digitalWrite(9,LOW);
delay(30);
digitalWrite(9,HIGH);
delay(100);
digitalWrite(9,LOW);
delay(30);
digitalWrite(9,HIGH);
delay(70);
digitalWrite(9,LOW);
delay(30);
digitalWrite(9,HIGH);}

// print the results to the serial monitor:
Serial.print(« sensor =  » );
Serial.print(sensorValue);
Serial.print(« \t output = « );
Serial.println(outputValue);

// wait 2 milliseconds before the next loop
// for the analog-to-digital converter to settle
// after the last reading:
delay(2);
