DIY Electronic Clock Kit SCM Digital LED Clock Set With Acrylic Shell ATMega328 DIP IC Low Power CR2032 Button Cell Powered
Description: The heart of the kit is the much venerated ATMega328 using a 32kHz clock-source to keep time. To check the time, just press the button on the side of the clock and it pops up on a 4-digit 7-segment LED display. the ATMega is running at super low power and should get an estimated 2 years of run time on a single CR2032 button cell. The DIY clock is a through-hole kit with a low parts-count, so it makes a great project for beginning solderers. After you've finished soldering together the PCB, simply stack the acrylic pieces around it and screw them together with the included screws. Once that's done, pop in the coin-cell battery and go show off your nerd bling.
