Blank Serial Monitor

Hi,
I've just installed Arduino IDE and bought a Grove Beginner Kit, trying to make a mini car race game with Unity. Since I'm learning Arduino, I clicked the Example sketches and clicked the 01.Basics - AnalogReadSerial. So as I suppose, the values of sensors should appear on my Serial Monitor for each millisecond, but it's blank, although I've connected the Grove Beginner Kit to my pc (PWR light on).

Also I have downloaded the CP210x_Universal_Windows_Driver, since I'm using Windows. I also checked in the Device Manager that it's put on COM5, thus I modified my Arduino setting to:
Board: Arduino Uno (checked a tutorial)
Port: COM5

I also checked the Bits per Second: 9600, which is exactly the same to 9600 Baud in Serial Monitor.

Can someone help me??

Down below the codes:

void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
  // read the input on analog pin 0:
  int sensorValue = analogRead(A0);
  // print out the value you read:
  Serial.println(sensorValue);
  delay(1);        // delay in between reads for stability
}

Yes

The PC should be connected to the USB connector on the Arduino UNO. Try without the "Grove Beginner Kit" connected to your Arduino UNO.

Did you upload the code to the UNO?

I only have the Grove Beginner Kit (for Arduino) which has things like Buzzer, OLED Display, Pushbutton, Rotary Potentiometer etc.. I don't have the Arduino UNO, which I suppose they are the same kind of kit to use for programming on Arduino IDE.
I have connected the Grove Beginner Kit to my pc via USB, and since the light of PWR was on, I assume it's connected...

Then what "Arduino" are you uploading the sketch to? Until you upload a sketch to an Arduino you can't expect it to do anything.

But aren't they the same kind of kit, where you can connect wires between cables? Or is Arduino UNO a special necessary kit that functions like a connector between my Grove thing and pc?

My mistake! I thought the "Grove Beginner Kit (for Arduino)" was a set of accessories that you can connect to an Arduino UNO. On closer inspection it appears that the main board in the kit has a processor on it. I think the main board should be treated like an Arduino UNO. If you uploaded the sketch without problems I don't know what could be keeping it from displaying text on Serial Monitor. :frowning:

Dw. I think I found the problem. It seems that I need some codes to integrate with Arduino made by Grove... Searching the right ones on Github now. Hoping that this time everything will be fine. :pensive:

Lol I found the problem. I have set the wrong Sketchbook location in the Preferences. That's why nothing is appearing in the Serial Monitor.
Thanks for your help tho, sorry for occupying your time.

No problem. We were all new here once.
