Serial.Results are output to the Serial monitor window.Īll of the I2c.write functions return values that can be used for error checking and troubleshooting. Serial.print('I2C device found at address 0x') a device did acknowledge to the address. The i2c_scanner uses the return value of While (!Serial) // Leonardo: wait for serial monitorįor(address = 1 address < 127 address++ ) * if you are sharing this code, you must keep this copyright note. * Please view other Robojax codes and videos at It will display the I2C address as 0x3C or similar. Just upload the code into your ArduinoĪnd open serial monitor and wait. This program will find the I2C address on the I2C device.
