For the thermistor, you canuse the code from the previous labs to convert the ADC value into the Fahrenheit temperature. Since theADC on the Arduino is 10-bit instead of 8-bit, which is what we were getting over the serial port, you willneed to adjust the ADC to voltage calculations appropriately.For the photoresistor, you will need to convert the ADC value into a light intensity. As the light levelchanges, the resistance of the photoresistor (Rp) will change - specifically, the resistance changesaccording to the following formula: R₂ = R₁ where L is the light intensity. In other words, RP isinversely proportional to L. The analog voltage that you will be measuring is given by the voltage dividerformula Vana-R+1Knwhere Vana is the analog voltage. As with the thermistor, you will need to convertthe ADC value that you get from analogRead into a voltage. Once you get the voltage, you can use theabove formulas to calculate L which is what your Light Sensor::read method should return.Assume that RoLo = 20000.5V-1KNFinally, the setup code will create an array with pointers to the two sensors. The loop code will selectwhich sensor to display using the sensorno variable. The user can select which sensor they want todisplay by sending '0' or '1' in the Arduino serial monitor. You will need to add some code to check ifthe user has sent anything by calling Serial.available (), and if any data is available, callSerial.read() to get the data. Check if it is '0' or '1', and change sensorno appropriately. Notethat the Arduino serial monitor will also send a newline ('
') character in addition to the '0' or '1'.So, you can just ignore any character that is not a '0' or '1'To bring up the serial monitor in the Arduino, click the serial monitor button at the top right of the Arduinowindow.
