Have an old cell phone laying around? Don’t know what to do with it? What if I told you that you could turn that old cell phone into a smartwatch!?!
This code is intended to be installed on an Arduino to be used for a smartwatch. The smartwatch utilizes an LCD screen from a Nokia 1100 cell phone. You can find details about the build at this link: http://www.tinkernut.com/portfolio/make-smartwatch-old-cell-phone-part-1/
