Breadboard ATMEGA328 upload problems

Projects General Guidance

Arduino on a breadboard. I am using the following:

ATMEGA328P-PU chip with bootloader 16mhz G36 (kit)

5V 3.3V FT232RL USB to Serial Adapter Download Cable Module for Arduino

I've attached a picture and the code. Compiles ok but does not upload. After about a minute trying I get the 'Problem uploading to board' message. I've searched for a solution but to no avail.

Under tools in the IDE, I get:

Board: "Arduino Nano"
Processor: "ATmega328"
Port: "Com8"

I've checked with the Device Manager and confirm Com8 is correct. The board and processor above showed up the first time I plugged it in. I tried changing the board to "UNO" just to see what would happen. The Processor line disappeared. Did not upload also.

I am using the setup provided on youtube by Educs8.com "Arduino Uno (ATMEGA328P) on a breadboard Tutorial DIY project. Easy guide."

Would appreciate any suggestions. I am really interested in building a low power setup but stumped here for now.

Thanks for helping

The ATmega328P needs 5V and GND on both sides of the chip (but not to AREF).

Thanks for the reply. I don't see those connections on the working project on the youtube tutorial though. The picture on my layout is the same as the tutorial project. hmm...

Comment this out & try it:

LowPower.powerDown(SLEEP_8S, ADC_OFF, BOD_OFF);

Thanks. No dice on that suggestion. Same result.

I notice that when the IDE goes from Compiling to Uploading.... the blue LED on the USB to Serial adapter does not flash. The red LED near the pins is lit though.

Also, this error message appears at the bottom of the IDE page when uploading fails:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xfd

Hope this helps.

Problem solved. Not sure how....rebuilt circuit and after several attempts is now uploading....
