!!!!!  
when i input a color(like bleu or green or red ) to the arduino the if loops doesnt seem to think that the condition is verified even though the speling is not wrong .  
!!!!!!

```cpp
int redled=10;
int bleuled=9;
int greenled=8; 
String chosen;
int j;
String msg1="what led would you like to light up .";
void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);
pinMode(redled,OUTPUT);
pinMode(bleuled,OUTPUT);
pinMode(greenled,OUTPUT);
}
void loop() {
  Serial.println(msg1);
  while(Serial.available()==0){}
  chosen=Serial.readString();
  Serial.println(chosen);
      if(chosen=="green" ){
    digitalWrite(greenled,HIGH);
    digitalWrite(redled,LOW);
    digitalWrite(bleuled,LOW);
    j=1;
    }
      if(chosen=="red" ){
    digitalWrite(redled,HIGH);
    digitalWrite(greenled,LOW);
    digitalWrite(bleuled,LOW);    
    j=1;
    } 
      if(chosen== "bleu" ){
        digitalWrite(redled,HIGH);
        digitalWrite(redled,LOW);
        digitalWrite(greenled,LOW);
        j=1;
    }
    Serial.println(j);
      if(j!=1){
        Serial.println("invalid color please chose from the folowing :");
        Serial.println("bleu,red,green");
         digitalWrite(redled,LOW);
         digitalWrite(greenled,LOW);
         digitalWrite(bleuled,LOW);
        
        }
}

```

Change the line ending setting on the serial monitor to "none"

You can go back and edit your original post to include code tags. Just highlight the code and click on the **\</\>** in the menu bar. It is that simple.

are you certain about the commands for the "bleu" light ?

```cpp

```

if(chosen== "bleu" ){  
digitalWrite(redled,HIGH);  
digitalWrite(redled,LOW);  
digitalWrite(greenled,LOW);  
j=1;

```cpp

```
