Hi,
I am trying to install ADT7420 digital temperature sensor to Arduino Nano.
I have written a sketch for Arduino UNO, it works on Arduino UNO very well.
But same sketch couldn't work on Arduino NANO :~
Could you kindly tell me what is wrong?
Please help me
#include <I2C.h>
#define ADT 0x48
int i,ans;
long temp;
double celsius;
void setup()
{
I2c.begin();
Serial.begin(9600);
delay(10);
I2c.read(ADT,0x0B,1);
byte st=I2c.receive();
Serial.print("ID:(0xCB):");
Serial.println(st, HEX);
}
void loop()
{
int i;
byte xH,xL;
Serial.print("temp:");
I2c.read(ADT,0x0,2);
xH = I2c.receive();
xL = I2c.receive();
/*Serial.print(xH,HEX);
Serial.print(xL,HEX);
Serial.print(": ");*/
celsius = double(long(word(xH,xL)) * 100/128)/100.00;
Serial.print(celsius);
Serial.println("deg");
delay(500);
}
I use SCL as A5, SDA as A4.
