This is a kit for a clock shield for ProMini (Arduino-compatible mini board). Time is displayed as HH.MM, with a flashing dot, on a 7-segment bubble LED display. The clock is based on DS1307 RTC, with an-board backup battery. Hours and minutes are set by pressing the two buttons respectively.
This is the only clock kit I know that uses the bubble 7-segment display. Since most of the components are SMD, it should be a good introduction to SMD soldering.
Small clock gadget, possible to power directly from a 3.7V LiPo battery. Current draw is 15mA on average (including the ProMini, without the 2 LEDs on-board).
There seem to be more than one kind of ProMini. This shield requires the kind that has A4 and A5 as shown in the last photo.
