sorry for the total newb question, when I hook up my uno and write the code for a simple LDR circuit
int sensePin =0;
void setup(){
Serial.begin(9600);
}
void loop (){
Serial.println(analogRead(sensePin));
delay (500);
}
should I be getting output in my serial monitor after uploading this code

If the serial monitor is open and the serial speed matches, I don't see why not
Please remember to use code tags.

thanks for the reply AWOL
serial speed matches?? where do I check this?? 9600 is standard for PC an Arduino correct??
You check it at the bottom of Serial Monitor where you select the speed.

It's a good idea to put a Serial.println() line in setup() to let you know that communication is working
For example
void setup(){
Serial.begin(9600);
Serial.println("Arduino program NNN has started");
}
where NNN is the name of your program.

And you can even get the sketch to report its own name
void setup ()
{
Serial.begin (115200);
Serial.println (F(__FILE__ " starting"));
}

Neat. I must remember that.
