Outcome

GOAL:

A) Give a visual cue, through a green LED, to warn user that water is above boiling temperature (temperature sensor reads if water is above 212F);

b) Give visual cue, through a green LED, to warn user that lid on cooking pot is not properly closed (light sensor detects light coming from openings between pot and lid);

The first assembly of the circuit board yielded in the LEDs never turning on, although the LEDs themselves were installed using the same diagram as the previous tasks in class (and were initially blinking because the Core was running the old program), which means there was a problem with the assembly of the sensor circuitry.

After tweaking the circuitry by looking at resources at the internet (such as: http://playground.arduino.cc/Learning/PhotoResistor), it was possible to get the LEDs to blink and react to the sensor readings. However, the readings were expurious and the LEDs were working because the temperature sensor was reading rooms temperatures above 212F, and the light sensor was detecting light permanently.

RESULTS: The results were mixed. Although it was possible to use the knowledge gained in earlier classes as building blocks to this larger creative project - with the aid of internet resources - and come up with a code that worked with no problems, I had trouble in correcting the sensors readings to get the necessary accuracy. 

I believe the main problem was lack of experience in circuitry building, which might have led to errors that caused the expurious readings.
