/*Header
  Hardware and programming to better understand and use analogRead

    In this cricuit we have a potentiometer - a variable resistor
    Which by turning the knob (changing the resistance) we can 
    change the amount of voltage the potentiometer disappates
    For you circuits wizzes a potentiometer is variable voltage divider
  Think about how we could display and view readings
  and how we could use those readings to alter other functions

  In this example we want to use those readings to let us know
  IF the reading is below a value, and IF so, we should print 
  a statement to the serial monitor
*/

//Global variable and pin delcaration
//are using analog pin A0 --> already declared
//pins declared

//variables?
int Bread; //analog reading from potentiometer (A0)
int BreadMapped; //new mapped value


void setup() {
  // put your setup code here, to run once:

  //no need to pinMode

  //initialize serial monitor plotter
  Serial.begin(9600);

}

void loop() {
  // put your main code here, to run repeatedly:

  //now read/sense voltage from circuit | sensor/ read-command
  Bread = analogRead(A0);
  Serial.println(Bread);
  

  //I want to display 'LEFT' IF the value is below half-the 10bit value
    //and 'right' if the value is above that 10-bit value
  if(Bread <= 512){
    //where everything happens IF true
    Serial.println("LEFT");
  } else {
    Serial.println("RIGHT");
  }

  //if(condition){
    //do stuff IF TRUE
  //} else {
    //do stuff ELSE TRUE
  //}



  //Now these values correspond to what range of voltages?
  //what if I wanted that voltage instead of the 10bit value
  //we can MAP a value in a specified range to a value within another range
  //0-5V


  //map funciton 
  //BreadMapped = map(Bread, 0,1023,0,5); //all integers 0-5

  //get creative use map to get voltage to x.xx
  //BreadMapped = map(Bread,0,1023,0,500);//all 0-500 just divide by 100

  //can I map to negative values and other directions
  //two numbers: 50 -412
  BreadMapped = map(Bread,0,1023,50,-412);
  //YES - negative values and OTHER DIRECTIONS


  Serial.println(BreadMapped);




  //add a nice little .1s delay for viewing purposes
  delay(100);//ms
