You have a thermistor (a varying resistor), a 10 kohm resistor, and an Arduino board. Draw a circuit diagram to measure ambient temperature. You can draw a rectangle to represent the Arduino board, but you need to show which pins are used.
Homework Answers
In the above circuit what is happening is,
The first pin of thermistor is given positiove 5 v supply from 5v pin of Arduino
The second pin of thermistor is connected to resistance in series and is connected to To A0 pin of the Arduino.
As thermistor changes the resistance within it, which in turn changes the voltage that is potential drop across the output pin of thermistor. So this variation in analog voltage is converted into the digital form by Anolg To Digital converted pin A0 of Arduino.
The resistance 10 k is further connected to ground to complete the circuit and protect the thermistor.

op amp LM358N is used. This device is actually temperature
measurement. Instead of resistor of 174Ohms, it should be a RTD or
PT100, but I don't have in the lab right now, so this is
simulation. With this resistance, temperature should be around
188-189 Celsius. I hope this part is clear. In the lab, for
different temperatures I will put different resistor, 190 Ohms, 280
Ohms etc. Output of the amplifiers should be connected to pins A0
and A1 on...

This question is about the Arduino code.
Please complete a 4-input circuit on your Arduino. Your circuit,
in addition to cycling through a binary representation of the
numbers 0-15 using LEDs, should use the Serial port to output the
decimal equivalent of each of the numbers in the format:
Output: 15
... if the value was 1111, and so forth.
You will be asked to upload your code as well as a photo of your
