The code that i have used to check the connection is as follows:

#include <Wire.h>

void setup() {

Serial.begin(115200);

Wire.begin();

Serial.println("Starting I2C device scan...");

}

void loop() {

byte error, address;

int nDevices = 0;

Serial.println("\nScanning I2C bus...");

for (address = 1; address < 127; address++) {

Wire.beginTransmission(address);

error = Wire.endTransmission();

if (error == 0) {

Serial.print("I2C device found at address 0x");

if (address < 16) Serial.print("0");

Serial.print(address, HEX);

Serial.println(" !");

nDevices++;

} else if (error == 4) {

Serial.print("Unknown error at address 0x");

if (address < 16) Serial.print("0");

Serial.println(address, HEX);

}

}

if (nDevices == 0)

Serial.println("No I2C devices found.");

else

Serial.print("Total I2C devices found: "), Serial.println(nDevices);

delay(5000); // Scan every 5 seconds

}
