Using Arduino Uno to Measure Lux

I bought my module from my local electronics shop, so I don't know this link will be useful to you, but here it is anyway: http://elelsu.com. In response to your other questions/suggestions:

  • yes, I am using a breadboard, and this time, I connected all my jumper wires directly to the GY-30 module.

  • I connected VCC to the Arduino's 5V

  • I disconnected the modules ADD pin

  • I ran the I2C scanner again

Despite doing all of the above, this time, when I ran the I2C scanner, I got the following error message:

avrdude: ser_open(): can't set com-state for \.\COM3
An error occurred while uploading the sketch

Just so you know, my baud rate is correct.

Considering all of the above, could anyone tell me what I am doing wrong?
