Arduino UNO doesn't work, sync error

Development Tools IDE 1.x

PLEASE HELP ME!!!

I'm new in Arduino and I have problems when I upload any code to my Arduino UNO board. I read lots of comments and try quite a lot solutions but I still having the problem.

I already have checked the serial port, update the drivers, verify if the selected Arduino board is the correct, disconnect the RX and TX pins from any cable, check if the bootloader exists by putting a led on pin13 and so on. Even reprogram the bootloader from another Arduino UNO board but nothing works.

Arduino IDE 1.6.4 shows me this:

avrdude: stk500_recv(): programmer is not responding

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xd6

Sometimes changes from 'resp=0xd6' to 'resp=0xc0' and others everytime I try to upload the code.

:confused: :confused: What can I do??? :confused: :confused:

:cry: :cry: :cry: Please HELP ME!!! :cry: :cry: :cry:

"putting a led on pin13"

If your "Arduino" didn't come with an LED on Pin 13 it is not an Arduino Uno. Perhaps that is the problem.

Well, I did it because I read it in one of the comments in the foroum. My Arduino comes with the led which is above the RX and TX led with the 'L' letter. I put the led on pin13 because I wanted to check if my bootloader is burned in the chip and default led was fine.

Can you give me another solution?

I'm brand spanking new to Arduino; got it three hours ago.

I'm not familiar with 1.6.4, have 1.6.6. There are two options, upload and programmer. As your error is refering to programmer, if 1.6.4 has the upload option, you can try that.

I hope it helps

Since you have the Arduino Uno with all the LEDs you can learn much from the blinking of the lights. For each of the three lights (L, RX, and TX), what do they do when you:
A) Press the Reset button.
B) Attempt to upload a sketch.

Couple questions.

  1. Is it a TRUE arduino or a clone ?

  2. What is your current operating system ?

  3. What (if any) other boards are you using at the moment ?

I only ask as it sounds a little like a comms error and that could be a couple of different issues.
If its a newer clone and its not a true FTDI chip it could be that you need the CH340 drivers.

OR

If it is a clone with a copy FTDI chip it could be that you need to unlock the comms ports and do some windows updates (presuming windows but I am bound to be wrong)

Hate to say this but did you upgrade to 1.6.6 or do a full fresh install ?

(BTW I am not against 1.6.6 but seeing so many issues in its use right now I have to ask ;D )

I'm running Windows 10 Home Edition. My Arduino seems to be a clon one. Don't have any other board in use. I've been surfing and found a solution for the Drivers, I installed them but don't notice any change. The error still there.

Can you give me possible solutions for com ports? Like unlock them or modify something to fix my board?
