[kruzzlo]

Hello, could someone help with uploading sketch for Bluetooth RC car, i got this error and all kind of fix i tried did not work.
Thank you

Welcome to the forum

Which Arduino board are you using ?
Are you by any chance using pins 0 and 1 for your Bluetooth serial connection ?

Please post your full sketch

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use code tags (the </> icon above the compose window) to make it easier to read and copy for examination

MOD edit - fixed code tags

Looking at your code, I guess that post #2 was right about the cause.

[kruzzlo]

I'm using pins 0 and 1(RX, TX) for bluetooth, but what am i supposed to do with it , sorry for not understanding, it's like my second project with arduino.

[amitf]

Just disconnect the Bluetooth when uploading your code

Check if it works

[kruzzlo]

didn't work

[UKHeliBob]

Disconnect everything from the Arduino except for the USB lead. Can you upload the Blink example ?

If so, then can you upload your sketch ?

What is connected to the Arduino to make your car work ? How is the car powered ?

Seeing a schematic of your project would be helpful

[kruzzlo]

Blink works fine, car is powered by 4, 1.5 V batteries through DUAL H-BRIDGE MOTOR DRIVER L298N, but i cannot upload sketch

[sterretje]

Did you disconnect the Bluetooth module before starting the upload? Your diagram shows that it's connected to pins 0 and 1. See post #2.

@kruzzlo

i cannot upload sketch

That is almost certainly because you are using the same pins (0 and 1) as the Serial interface that is used to upload code. Disconnect the Bluetooth module and try an upload

[kruzzlo]

uploaded succesfully, thank you

[UKHeliBob]

The problem would have been identified earlier if you had answered the question about the pins being used in reply #2

Do you understand the problem ?
