Installation of retrowatch

im expecting to see the time display, the project is supposed to like a smart watch just that now its a glasses,

can i clear the coding and start again

do you have a coding to program the retrowatch on arduino nano

Due to this being a first time for coding, i am not sure how to find the correct code to load onto the OLED.

The coding needs to be a retrowatch working together with a HC- 05 Blue tooth
