Have error code " avrdude: Expected signature for ATmega 328p is 1E 95 0F Double check chip .or use -F to over ride see attached
the chip stamp has AMEL 3547D Atmega 328 U 2049HRR ( I order a ATmega 328 PU but 328 u -this is what they sent me ))
NOT SURE WHAT TO DO -Need GUIDANCE
and if I do a -F where do I insert it ?
I followed the directions in the tutorial , use the schematic , Wiring is okay , communication okay but this error
I noticed that the chip in mu UNO board is AMEL 35473D Atmega 328P U 2025SJJ
Is this causing a issue ?
Just ignore -F, it doesn't help.
Switch on the more detailed info for uploading in the preferences.
Check the circuit again.
It can be difference in the MCU. There are various 328 on the market and 328P differs in signature from 328 (1E9514), it could be the problem. Check it according the datasheet.
Different packages , versions, temperature ranges etc if the chip report back different device signatures. If that number is not recognised by the IDE it throws an error .
You can add your new signature , this might help :
You have cut off the most important part of the error message. The most common causes of this error can not be fixed by -F or by editing avrdude.conf, so please don't waste your time and potentially mess up your toolchain by going down either of those rabbit holes until we have completed the minimal initial investigation.
Please do this:
- Tools > Burn Bootloader
- After the Burn Bootloader process fails, you'll see a button on the right side of the orange bar: "Copy error messages". Click that button.
- In a forum reply here, click on the reply field.
- Click the </> button on the forum toolbar. This will add the forum's code tags markup to your reply.
- Press "Ctrl + V". This will paste the Burn Bootloader output between the code tags.
- Move the cursor outside of the code tags before you add any additional text to your reply.
This procedure is what you should always follow when asking for help with error or warning messages on the forum. Posting screenshots of text is not very helpful.

I included all the complier warnings when back to preferences included " all "
OK, very good. So it is recognizing the signature correctly, rather than the thing that happens 99% of the time where the signature check fails because the chip is not recognized at all.
My recommended solution is to use MiniCore:
After installing it, you'll be able to select Tools > Board > MiniCore > ATmega328, then Tools > Variant > 328 / 328A. After that, you'll have no problems with the signature because the Arduino IDE will be configured for the chip you have.
Because the ATmega328 and the ATmega328P are identical in every way that matters for these purposes, the other options will work as well: running avrdude from the command line with the -F flag to cause it to ignore the signature mismatch, or editing avrdude.conf as @hammy recommended. Those are slightly more complex than the MiniCore approach, but not by much.
Looks like you got an ATmega328-PU instead of an ATmega328P-PU. The 'P' after 328 is important.
One way to work around the problem is to find a 'board' declaration that uses the 328. The declaration for the UNO in boards.txt is:

The only change is from mcu=atmega328p to mcu=atmega328. If you select this board type before burning a bootloader it should expect a 328 instead of a 328P.

Now it does not seem to recognize the chip I'm going to re order make sure I get ATMEGA328P-PU
thanks for you help Oh I did check all my connections
I bought some 328 (no P) chips by mistake and using the, previously mentioned, MiniCore make it a breeze to bootload them. Besides, if you bootload to 8MHz internal you get 2 more GPIO pins.
aedford1551:
avrdude: Device signature = 0x000000
avrdude: Yikes! Invalid device signature.
This is the signature error we see more often.
Carefully check the wiring between the programmer and target.
I see a crystal in the circuit diagram on the tutorial you are following. Do you have one on your circuit? Make sure it's wired correctly.
