I'm at my first project on arduino and I can't figure out what the problem is with my coding. It says
collect2: error: ld returned 1 exit status
exit status 1
Erreur de compilation pour la carte Arduino/Genuino Uno
Ceci est mon premier projet sur arduino et je ne trouve pas mon erreur de codage.
Here's my code / Voici mon code:
void loop(){
int pinUn = 1;
int pinDeux =2;
pinMode (pinUn , OUTPUT);
pinMode (pinDeux , INPUT);
if (pinDeux == HIGH){
analogWrite (pinUn , HIGH) ;
delay (500);
analogWrite (pinUn , LOW);
delay(1000);
}
else{
for(int pwr=0 ; pwr < 200 ; pwr ++ ){
analogWrite(pinUn , pwr);
};
};
}
I added up a setup, now Arduino do not point any error but when i upload it it does not work, the led stays off
void setup(){
int pinUn = 1;
int pinDeux =2;
pinMode (pinUn , OUTPUT);
pinMode (pinDeux , INPUT);
}
void loop(){
int pinUn = 1;
int pinDeux =2;
pinMode (pinUn , OUTPUT);
pinMode (pinDeux , INPUT);
if (pinDeux == HIGH){
analogWrite (pinUn , HIGH) ;
delay (500);
analogWrite (pinUn , LOW);
delay(1000);
}
else{
for(int pwr=0 ; pwr < 200 ; pwr ++ ){
analogWrite(pinUn , pwr);
};
};
}

hello
ICI
int pinUn = A0;//attention, ce n'est plus 1 mais A0
int pinDeux =2;
void setup()
{
pinMode (pinUn , OUTPUT);

void loop(){
if (pinDeux == HIGH)
{
analogWrite (pinUn , HIGH) ;
