Basic Assembly and Setup

So my problem is, that when I try to upload my code from arduino it works until the end, the lights from the FTDI uploader are blinkin, and then it says that the upload failed. I am at the beginning of uploading of the codes and startet with the test buzzer code and it don’t work.

I hope someone can help me, because I need to finish my nybble cat until Monday (09.11.2020) and I don’t know what’s wrong. 🥺😓
