Being new to arduino, ive tried an analogue input. My aim was to turn on the built in LED when the input voltage at pin A0 reaches X amount. Ive written the code below, and tried varying values for the threshold figure but cannot get the led to turn on. I have 1 volt going into A0 at the moment but …

Simple code not doing what i hoped.
