Hey Everyone! Please help me, it's so serious! I would like to make a code for a shutter control in C++, here's the code:

Question

void setup() {
Serial.begin(9600);
pinMode(8, OUTPUT);
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);
pinMode(11, OUTPUT);
//digitalWrite(11, HIGH);
}

void loop() {
commandState = analogRead(A0);
Serial.println(commandState);

if(commandState == 0 && commandState <20){
digitalWrite(11, HIGH);
digitalWrite(10, LOW);
digitalWrite(9, LOW);
digitalWrite(8, LOW);
}
else if(commandState > 683 && commandState < 723) {
digitalWrite(11, LOW);
digitalWrite(10, HIGH);
digitalWrite(9, LOW);
digitalWrite(8, LOW);
}
else if(commandState > 94 && commandState < 134) {
digitalWrite(11, LOW);
digitalWrite(10, LOW);
digitalWrite(9, HIGH);
digitalWrite(8, LOW);
}
else if(commandState > 394 && commandState < 434) {
digitalWrite(11, LOW);
digitalWrite(10, LOW);
digitalWrite(9, LOW);
digitalWrite(8, HIGH);
}
delay(50);
}

Assuming you're trying to code on Arduino, I think you need to put 'int' before the first commandState (right after loop(){) to declare.

if it's not an compile issue, you could explain problems more.
