The digital clock I plan on making is a battery powered, Arduino clock. The whole project will encompass coding the program, creating push buttons to set the date/time on the LCD display, integrating push buttons to be able to set time and day, and 3D printing a housing along with making the entire circuit battery powered. The plan thus far is to make an external battery bank that is replaceable/rechargeable. A final photo from the project being referenced is cited below.
