ENGR 103 Final Assign

For this project, I used a thermistor to measure temperature data in my dorm room over 24 hours. I was originally going to use the LM75A Temperature sensor for this, however, I could not get accurate readings from it and switched to using a thermistor. The circuit is powered by the 3-volt pin, uses a resistor, and has an output connected to pin 34. My code takes the analog reading from the thermistor every second, and converts the raw output into degrees Fahrenheit using a nested for loop. The outside for loop then calculates the 10-minute average and prints the data from each 10-minute interval. I also used the millis() function to print the time since the program started at the end of every 10-minute interval. I started collecting data at about 9 am. Strangely, the temperature in my room got colder during the day, and warmer during the night. I assume this is because my heater turns on at night and off during the day.
