Profiling Machine: First Attempt

In our first discussion/brainstorm our team centered on the idea of a profiling machine.  The machine would take the form of a dial controlled by a servo that points to right or wrong answers.

The first idea was to control the servo angles using discrete push buttons.
This failed miserably.

Code:

/*A Moral technology by Breadboards are us
this code combines an Alternating switch program with a servo
position program to create an (im)moral profiling machine*/

#include <Servo.h>

Servo myservo;  // create servo object to control a servo
int pos = 0;  //variable to store the servo position

int switchPin1 = 1;  //switch is connected to pin 1
int vaLone;  //variable for reading the pin status
int buttonState1;  //variable to hold the last buttonState

int switchPin2 = 2;  //switch is connected to pin 2
int vaLtwo;  //variable for reading the pin status
int buttonState2;  //variable to hold the last buttonState


void setup()
{
 myservo.attach(9);  // attaches servo on pin 9 to the servo object
  pinMode(switchPin1,INPUT); //Set the switch pin as input
  pinMode(switchPin2,INPUT); //Set the switch pin as input
  Serial.begin(9600); // Set up serial communication at 9600bps
 buttonState1 = digitalRead(switchPin1);  // read the initial state
buttonState2 = digitalRead(switchPin2);  // read the initial state

}

void loop()
{
  vaLone = digitalRead(switchPin1);  //read input value and store it in val
  //if (vaLone != buttonState1)  {  //the button state has changed!
  if (vaLone == HIGH)  {  // check if the button is pressed
  pos = 10;
  myservo.write(pos);  //if it's pressed send it to angle 20
  }
  else  {  //the button is not pressed
    pos = 0;
  myservo.write(pos);
  }
 
buttonState1 = vaLone;  // save the new state in button's variable

  vaLtwo = digitalRead(switchPin2);  //read input value and store it in val
  //if (vaLtwo != buttonState2)  {  //the button state has changed!
  if (vaLtwo == HIGH)  {  // check if the button is pressed
  pos = 180;
  myservo.write(pos);  //if it's pressed send it to angle 20
  }
  else  {  //the button is not pressed
    pos = 0;
  myservo.write(pos);
  }
 
buttonState2 = vaLtwo; //save the new state in button's variable


}
