Hi, still having troubles getting it to upload. Prolly going to request for a replacement

I deleted the Libraries from the Arduino and ArduinoData folder however the stack trace remains the same. Despite this, it does say how much space is used. However, now when I try to upload and open the serial monitor I get this error-- I found a good article (attached below) listing a few thigs to try but I'm curious if this is a common issue among others. https://arduino.stackexchange.com/questions/17/avrdude-stk500-getsync-not-in-sync-resp-0x00-aka-some-dude-named-avr-won

I think I just need to update the driver--which Usegundo suggested as well.

Hi, sorry for the late response-- I'm running Windows 10 and I looked for it under the Arduino IDE (tools --> port, which is grayed out) and device manager which shows all my COM ports but when I plug in Nybble a little yellow triangle with a black exclamation point appears over FT232R USB UART. I'm thinking I need to update that driver? Below are pictures of what you asked for.

Worked perfectly! Thank you!

Hi Mr. Li, I'm using Nitecore Rechargeable Li-Ion 14500 3.7 volt batteries. Attached is a video of the connections, let me know if I need to retake it. Additionally two pictures of components I had to resolder (the IR sensor for the remote, and some gray box which I don't know the name of, respectively). Thank you for the information and the help.
