Rock around the LEGO clock!
This is an old-fashioned analog LEGO clock with the minute and the hour hands. A single EV3 Medium motor drive the whole mechanism through a gear galore!
You can build this LEGO clock out of a singspeile LEGO MINDSTORMS Education EV3 set 45544, which includes a large variety of gears. This EV3 project allows you to use almost all of them together!
By building this analog LEGO clock, you will learn how to make gears mesh properly, and how to obtain precise gear ratios. The minute hand turns 12 times faster than the hour hand, thanks to a specially designed geartrain. This clock is designed to be programmed even with the simple Brick Program App.
