Hello i try upload a sketch for to my pro mini clone using the nokia 5110 lcd before i had no problem uploading a test sketch but for some reason I'm getting a error saying

What kind of usb-serial adapter are you using ?
I think the usb-serial adapter or perhaps the bootloader is wrong, or the wiring is not okay.
When I buy a cheap Pro Mini on Ebay, I always burn the newest bootloader to it. I don't trust the bootloader that came with it. It might have been written with a low voltage, or it might be a very old version.
It could be a counterfeit FTDI. It could even have been bricked by the FTDI drivers a few weeks ago.
Do you have another usb-serial adapter ?
Does the computer show a serial port ? If there is a serial port, the usb-serial adapter might be okay.
I don't have that specific Pro Mini board with labels BLK and GRN. But if it was working before, I assume it is okay.
Do you have a programmer, or are you willing to try to use an other Arduino board (like the Arduino Uno) as a programmer ?
FTDI works good i can use it on the other pro mini and even my uno breadboard i made. I even tried as different FTDI programmer and came out the same no difference. i even tried to program the pro mini clone with my Uno board and i get the same error.
Okay, two options: The Pro Mini bootloader is corrupted or it is broken.
Did you try your "Uno" to burn the bootloader ? If that is not possible, the ATmega328P might be broken. Or perhaps the crystal is broken. Did you drop it on a concrete floor ?
I think you have to give up on this one. Luckely they are only 3 dollars/euros. I bought one for 1.70 euros and it is working
Hello Peter i will try to burn the bootloader and no i didn't drop it never drop it. been on my desk for 3 weeks sense i last touched it. But i will try to burn the bootloader and see what happens.
yeah. the FTDI works good no problems its a real FTDI chip not a fake one. it works on my other pro mini and i even used it on my 328p chips and works with no problem just that one pro mini was giving problems.
