Projects General Guidance
1

I have already started the project based off another forum -
http://forum.arduino.cc/index.php/topic,151317.0.html

i need help with the code the one that was provided I believe is incorrect.
if anyone can help me with a code that would be wonderful.
im leaving out the buzzer which i dont need and my sensor is a Hc-sr04 different from the one that was stated in said forum. and for the power supple i am using a 3.3v/3.5v power supply

this is apparently the code that was provided just from looking at it i feel its missing alot or am i wrong

int sensorPin=0;
double segment=0;
double sensorVoltage=0;

void setup()
{


 pinMode(2,OUTPUT);
 pinMode(3,OUTPUT);
 pinMode(4,OUTPUT);
 pinMode(5,OUTPUT);
 pinMode(6,OUTPUT);
 pinMode(7,OUTPUT);
 pinMode(8,OUTPUT);
 
 Serial.begin(9600);
}

void sevenSegment(int number)
{
 
 
 switch(number)
 {
   case 0:
   PORTD=0b01000000; // 0
   PORTB=0b00000000;
   break;
   
   case 1:
   PORTD=0b11111000; // 1
   PORTB=0b00000000;
   break;
   
   case 2:
   PORTD=0b00100100; // 2
   PORTB=0b00000000;
   break;
   
   case 3:
   PORTD=0b00110000; // 3
   PORTB=0b00000000;
   break;
   
   case 4:
   PORTD=0b10011000; // 4
   PORTB=0b00000000;
   break;
   
   case 5:
   PORTD=0b00010010; // 5
   PORTB=0b00000010;
   break;
   
   case 6:
   PORTD=0b00000010; // 6
   PORTB=0b00000010;
   break;
   
   case 7:
   PORTD=0b01111000; // 7
   PORTB=0b00000000;
   break;
   
   case 8:
   PORTD=0b00000000; // 8
   PORTB=0b00000000;
   break;
   
   case 9:
   PORTD=0b00011000; // 9
   PORTB=0b00000000;
   break;
   default:
   // nothing
   
}
}
void loop()
{
  sensorVoltage=analogRead(sensorPin);
  segment=(0.018)*sensorVoltage-(0.2);
  delay(500);
  sevenSegment(segment);
}

Yes, you are correct. That code doesn't fit the schematic at all, and doesn't do anything but display digits on a seven segment.
