What's up with my code?

Question

Sorry if my code isn't well written or anything because I'm new to Arduino and coding in C, but what is wrong with my code?

int sidepin = 2;
int LED = 5;
int val;
void setup() {
  pinMode(sidepin, INPUT);
  pinMode(LED, OUTPUT);
}

void loop() {
  val = digitalRead(sidepin);
  if(val = 0)
  {
    pinMode(LED, HIGH);
  }
  else(val > 0) 
  {
    pinMode(LED, LOW);
  }
}

Answer 1

Your IF statement, you're using: (val = 0), and I believe you meant (val == 0).

Also, you're using else(val > 0) and else doesn't need any argument. So the fixed code should look like:

int sidepin = 2;
int LED = 5;
int val;
void setup() {
  pinMode(sidepin, INPUT);
  pinMode(LED, OUTPUT);
}

void loop() {
  val = digitalRead(sidepin);
  if(val == LOW)
  {
    pinMode(LED, HIGH);
  }
  else
  {
    pinMode(LED, LOW);
  }
}
