a. Based on the readings from the serial monitor, what is the range of the analog values being read?

0-10K

b. How many bits of resolution does the analog to digital converter (ADC) on the Atmega32U4 have (hint: where might you look to find this sort of thing)? How many are you using with the range of values you're seeing?

10 bits of resolution

a. Describe the voltage change over the sensing range of the sensor. A sketch of voltage vs. distance would work also. Does it match up with what you expect from the datasheet?

As an object gets closer to the distance sensor the voltage increases to a limit. If something get out of its range as in too close ir too far the voltage starts to go down again.

a. Include your accelerometer read-out code in your write-up.

*/

// these constants describe the pins. They won't change:

const int xpin = A3;                  // x-axis of the accelerometer

const int ypin = A2;                  // y-axis

const int zpin = A1;                  // z-axis (only on 3-axis models)

void setup()

{

  // initialize the serial communications:

  Serial.begin(9600);

}

void loop()

{

  // print the sensor values:

  Serial.print(analogRead(xpin));

  // print a tab between values:

  Serial.print("\t");

  Serial.print(analogRead(ypin));

  // print a tab between values:

  Serial.print("\t");

  Serial.print(analogRead(zpin));

  Serial.println();

  // delay before next reading:

  delay(100);

a. Upload a picture of your rotary encoder in action!

a. Turn in a copy of your final state diagram.

a. How many byte-sized data samples can you store on the Atmega32U4?

1000 bytes

b. How would you get your analog data from the ADC to be byte-sized?

take the analog
