 While switches and buttons are great, there's a lot more to the physical world than on and off. Even though the Arduino is a digital tool, it's possible for it to get information from analog sensors to measure things like temperature or light. To do this, we take advantage of the Arduino’s built-in-Analog-to-Digital Converter (ADC). Analog in pins A0-A5  can report back a value between 0-1023, which maps to a range from 0 volts to 5 volts.

+===== General Description  =====
 This uses a temperature sensor to measure how warm the skin is. This component outputs a changing voltage depending on the temperature it senses.
-It has three pins: one that connects to ground, another that connects to power, and a third that outputs a variable voltage to your Arduino.

 This is convenient because it outputs a voltage that changes directly proportional to the temperature in degrees Celsius.

+ ===== Software Design  =====
+I used the library LiquidCrystal_I2C.h in order to display on the I2C LCD the temperature. I am running the sketch TemperatureSensor.ino to make this work. I have initialized the pins for the temperature sensor and piezo. Then, in setup() I initialized the LCD i2c and I declared the pins for each LED. In loop() I read the value from the temperature sensor. By using 3 if's I set the LEDS to turn on based on the temperature.

+This is the final result. On the screen you can see the value of the temperature. Based on this value, the green LED turned on and the buzzer made a specific sound:
