+/*
+In this part of the Lab 3, you will make a digital thermometer using the SEN-11931 breakout board as well as the 4-bank seven-segment LED display.
+
+Study carefully chapter 7 regarding the digital temperature sensor provide in the lab kit, referring to the TMP102 datasheet and SEN-11931 
+breakout board schematics (under Weeks 5 & 6 --> Lab 3 Extra Files).
+
+Design the hardware connection of the SEN-11931, reusing the connection from part I of the this lab, 
+for the mbed to read the temperature from the SEN-11931 and display the temperature in Fahrenheit degrees on the 
+LED display in the format of xxx.x. Build your circuit and include all the required information about your hardware design in your lab report. 
+You will also need to make the decision on whether pull-up resistors are needed.
+
+Based on the hardware you designed, write a code that takes temperature measurement every 5 seconds and display the temperature in 
+Fahrenheit degrees on the 4-bank seven-segment LED display.
+
+Test your digital thermometer and explain your testing process and how you use your test results to confirm that your digital 
+thermometer functions properly.
