SHARP SENSORIN AVR ADC IS IS INBUILT SO THERE IS NO

NEED OF EXTERNAL CIRCUIT. THIS SHARP SENSOR HAS RANGE OF ONLY 10

TO 80 CM.WHEN IT IS OUT OF RANGE THAN IT GIVE

RANDOM VALUE OF DISTANCE.DUE TO THIS IN PROGRAM WE USE 0 VALUE

WHEN IT IS OUT OF RANGE.

PROGRAM TO SHOW DIS. ON SERIAL PORT#include

<LiquidCrystal.h>const int analogInPin

= 0; float sensorValue = 0;

LiquidCrystal lcd(4, 7,

8, 9, 12, 13);void setup() { lcd.begin(16, 2); }

void loop() { sensorValue =

analogRead(analogInPin);

lcd.setCursor(0, 0); if(sensorValue<80) sensorValue=0; else sensorValue = (6787 /

(sensorValue - 3)) - 4; lcd.print(sensorValue); lcd.print(" "); delay(100); }
