Michael, thank you very much for the response. I’ve already made the change in the code but I’m having some difficulty uploading. I have two laptops here, one of them running Ubuntu and the other running Mac OS X. Initially I thought it might be some problem with my drivers, although I’ve already uploaded it to other boards here. I could not upload and none of them, and I get the sync error message on avrdude:

avrdude: stk500_recv (): programmer is not responding
avrdude: stk500_getsync () attempt 1 of 10: not in sync: resp = 0x00

My question is this: do I need to put the 10uF capacitor between the DTR and the RESET pin of the ATMEGA328P or does the system work in the same way as the Arduino Mini (just connect the FTDI adapter to the Arduino pins)?

I just thought the upload would be done the same way I upload my sketches to the Mini, but that’s not working.

My FTDI adapter is the one here: https://www.amazon.com/Qunqi-FT232RL-Serial-Adapter-Arduino/dp/B014Y1IMNM and it has worked when I use the Mini Arduinos.

Another question concerns the voltage of the FTDI adapter. Mine has a 3.3V or 5V selection jumper. Which one would be correct?

Thanks in advance for your patience.
