Team Meeting 11/2213

We've come up with the circuit and code needed to run our design. A push button is used to turn on the system, an LED inticating its active, then a potentiometer then controls the speed of the motor driving the axles.

Here is the Circut:

The code:

const int buttonPin =  1;

int potpin = A0;

int motorpin = 4;

int analogread = 0;

int potvalue = 0;

int motorvalue = 0;

boolean currentState = LOW;

boolean lastState    = LOW;

boolean stateChange  = false;

int currentButton = 0;

int lastButton    = 2;

int ledArray[] = {13}; // setup

void setup() { 

pinMode(buttonPin, INPUT); 

for (int i=0; i<1; i++){   

pinMode(ledArray[i],OUTPUT); 

} 

Serial.begin(9600);

pinMode(8, OUTPUT);

  pinMode(9, OUTPUT);

  pinMode(10, OUTPUT);

}  // main loop

void loop(){

 potvalue = analogRead(potpin);

if(potvalue <= 600 && potvalue >= 400){

  digitalWrite(8, HIGH);

  digitalWrite(9, LOW);

  digitalWrite(10, LOW);

}

else{

  if(potvalue <= 800 && potvalue >= 601){

    digitalWrite(8, LOW);

    digitalWrite(9, HIGH);

    digitalWrite(10, LOW);

  }

  else{

    if(potvalue <= 1023 && potvalue >= 801){

      digitalWrite(8, LOW);

      digitalWrite(9, LOW);

      digitalWrite(10, HIGH);

    }

  }

} 

  currentState = debounceButton(); 

stateChange = checkForChange(currentState, lastState); 

currentButton = getButtonNumber(lastButton, currentState, stateChange); 

indicatorLight(currentButton); 

lastState  = currentState; 

lastButton = currentButton;

}  // function debounceButton

boolean debounceButton(){ 

boolean firstCheck   = LOW; 

boolean secondCheck  = LOW; 

boolean current = LOW;   

firstCheck  = digitalRead(buttonPin); 

delay(50); 

secondCheck = digitalRead(buttonPin);   

if (firstCheck == secondCheck){   

current = firstCheck; 

} 

return current;

} // function checkForChange

boolean checkForChange(boolean current, boolean last){ 

boolean change;   

if (current != last){   

change = true; 

} 

else { 

change = false; 

}   

return change;

}      // function getButtonNumber

int getButtonNumber(int button, boolean state, boolean change){ 

if (change == true && state == LOW){   

button++;   

if (button > 1){     

button = 0;   

}   

Serial.println(button); 

} 

return button;

}

int motorspeed(int potvalue, int mororvalue){

  potvalue = analogRead(potpin);

  motorvalue = map(potvalue, 0, 1023, 0, 255);

  Serial.print(motorvalue);

}

 

 

void indicatorLight(int button){ 

for (int i=0; i<1; i++) {   

digitalWrite(ledArray[i], LOW);

} 

digitalWrite(ledArray[button], HIGH);

if(button == 0){

potvalue = analogRead(potpin); 

 motorvalue = map(potvalue, 0, 1023, 0, 255);

 analogWrite(motorpin, motorvalue); 

 Serial.print("potentiometer = " );    

 Serial.print(potvalue);

 Serial.print("\t motor = ");

 Serial.println(motorvalue);

 delay(2);

}

else{

  analogWrite(motorpin, 0);

  digitalWrite(8, LOW);

  digitalWrite(9,LOW);

  digitalWrite(10, LOW);

}

    }

Couldn't get Github to work :(
