I'm not sure what kind of information you want from your board, but you can use the Arduino software to monitor messages sent over your serial connection from your chip. See that handy "serial montior" button? Just add a serial.print to your code and hit that button after your program is loaded.
int val;
void setup(){
Serial.begin(9600);
}
void loop(){
val=analogRead(0);
Serial.println(val);
}
