#include <LiquidCrystal.h>
LiquidCrystal lcd(8,9,4,5,6,7);//defining lcd pins
int value=0;//initializing variables
float volts=0.0;
float temp=0.0;
float tempF=0.0;
void setup()
{
pinMode(3,INPUT);//setting arduino pin3 as input
Serial.begin(9600);//opens serial port, sets data rate to 9600 bps
lcd.begin(16,2);//set up the LCD's number of columns and rows
}
void loop()
{
value=analogRead(A0);//read from A0
volts=(value/1024.0)*5.0;//conversion to volts
temp= volts*100.0;//conversion to temp Celsius
tempF=temp*9/5+32;//conversion to temp Fahrenheit
Serial.print("temperature= ");
Serial.println(temp);
lcd.setCursor(0,0);
lcd.print("TEMP= ");
lcd.print(temp);
lcd.print(" C");
lcd.setCursor(0,1);
lcd.print("TEMP= ");
lcd.print(tempF);
lcd.print(" F ");
delay(500);
}
请问各位大神，这段程序有什么问题？谢谢！！
