New User here, Unable to get pin input to work properly

Hello, I'm rather new to using the arduino and I've run into trouble trying to get my LED to blink when the arduino receives an input.

define Lin 6

void setup() { pinMode(11, OUTPUT); }

void loop() { if (Lin == HIGH) { digitalWrite(11, 150); delay(1000); digitalWrite(11, LOW); delay(1000); } }

Thank you for your time

 if (Lin == HIGH)

You need to use

 if (digitalRead(Lin) == HIGH)
digitalWrite(11, 150);

digital pins can only be HIGH or LOW, not 150
