Conflicting declaration

[MyNameIs-Nigel]

Hey! I was following your flashing tutorial on YouTube and found an issue that I am having. I can not compile the code because of an exit. "conflicting declaration 'typedef struct UPosition UPosition'"

How do you think I could go about resolving this issue? Here are the steps I followed to ensure you can run into this error:

1. Download the code from the github
2. Download arduino, rename the keebcard-master to keebcard
3. Open Keebcard.ino
4. Add TinyWireM.h and Tiny4kOLED.h libraries
5. Comment #define TETRIS and uncomment #define PONG
   Compile the code.

These are the exact steps shown in the video (to my memory) and resulted in the following error: (Info and such included in the error message)

Arduino: 1.8.9 (Windows 10), Board: "ATtiny25/45/85, ATtiny85, Internal 1 MHz"

Heyy! I just noticed I posted the Wrong error code! My bad!! Still, similar enough error. This error occurs on every one I have found.

Here is the updated error.

Hey there! I deleted everything except the necessary files and pong. So this leaves Keebcard, Pong.cpp, Pong.h, and settings.h.

Now it will compile.

Still not sure, is this a necessary step? As to my knowledge, you do not include this step in your video..
