Please read the advice in the topic "How to get the best from this forum". How to get the best out of this forum

I cannot read your post so "No Can Help" at this point.

Do you see the "COPY ERROR MESSAGES" button in your screenshot ? Use it and post what is copied in a new reply here using code tags when you do

I'm using arduino mega 2560.

Sketch uses 19278 bytes (7%) of program storage space. Maximum is 253952 bytes. Global variables use 1812 bytes (22%) of dynamic memory, leaving 6380 bytes for local variables. Maximum is 8192 bytes. avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_ReceiveMessage(): timeout avrdude: stk500v2_getsync(): timeout communicating with programmer Failed uploading: uploading error: exit status 1

The purpose of this project is to create a fingerprint attendance system.

  1. Did upload work in the past?
  2. Anything connected to pins 0 and 1? This will interfere with the upload so disconnect and try again.
  3. Anything else connected? Disconnect it and try again. If yes, what else is connected?
  4. Is COM3 indeed the Mega? Does the port disappear from the IDE's ports menu when you disconnect the board?
  5. If your board does not use the CH340 serial-to-usb converter but e.g. 16U2, what is the result of the loopback test?
  6. If you tap the reset button on the board, does the L-LED flash a couple of times?

I've moved your topic to the section of the forum that is dedicated to this type of problems.

The thread title is misleading , there is no any "exit status problem".
it is just an upload error

  1. Yes, and it works fine.
  2. Nothing is connected.
  3. The only components that are connected are LCD I2C and AS608.
  4. Yes, it is on COM3, but the port does not disappear even if it is disconnected.
  5. I don't know what this is.
  6. Yes, it blinks.

Thank you for your time just to reply.

If it does not disappear when disconnected, it's not the Arduino. I have no idea how to sort that out.

What does Windows think of your board? Check Windows device manager with and without the board connected.

Follow the link; but it's not useful if you can't find the correct port.
