Actually, this project is a digital clock that being used by using a 16×1 LCD display with 13mm high characters. With this way, it makes the display becoming easier to read. A Real Time Clock, where it’s an independent of the microprocessor is continuously updates the date/time. Beside that, the display is ideal for showing the information of other functions, example like the various temperature (it can be indoor or outdoor temperature), onboard voltage (V), battery charging current (A), the engine speed (rpm), fuel quantity (liters) and much more.
The best thing about this digital clock is the date and time is always visible on the display, although the engine is already turned off. However, you must pay attention that the contact is always on, as it will not keep the computer operating if it already turned off! Furthermore, you have to disable the contact on the display automatically time/date mode and handle the system in power-safe mode when it’s necessary. Read translated source here.
