* You can use this to verify values and behavior inside of a program, for debugging, for example:
** Displaying values of sensors : <code>val=analogRead(input_pin); Serial.print(val);</code>(assuming you've done the necessary setup).
** Checking program flow.
* Assuming you have a sensor which produces an analog output, hook it up to one of the Analog Inputs on your arduino. If you do not have a sensor, use the light sensor from last week. If you are not sure how your sensor works, come over and talk to me and we can try to figure it out.
