Updated Aug 30, 2014: A kit for this clock shield is now offered here . I am not particularly attracted by 7-segment LED displays, but I liked the HP bubble display that Sparkfun started selling recently. Like with the Nixie tubes, there aren't many things one can build with them, and my obvious choice was a clock. Being one of the smallest 7-segment LED displays out there, the clock had to be miniature as well. It took some thinking and planning to come to this final "design": This micro clock uses the Pro Mini sandwiched between the LiPo battery undershield and the display shield (that also includes the RTC), both DIY on protoboard. The LiPo undershield uses a cheap (less than $1 on ebay) USB charger board , which also provides the USB connector for power, since Pro Mini does not have one. The small 180mAh LiPo battery sits on top of the charger, but still allowing the 2 LEDs ("charging" and "charged") to be visible. There is also a switch for turn

I wrote up this post in response to the many inquiries I get about Arduino school projects. Here I describe how to build the most basic (and probably the lowest cost as well) Arduino clock, using a real time clock (RTC) chip and a 1602 LCD display (2 lines of 16 characters). Unlike most of the LCD clocks out there (the only notable exception being Kevin Rye's LCD clock ), this one is also encased and ready to be used in real life. Actually, the build starts with the enclosure (the very affordable adafruit LCD stand ), which drives the requirements for the rest of the components. Note: This LCD clock does not have any buttons. The time and date are set with the serial monitor (or Hyperterminal or any other serial console), by sending specific commands. I was thinking of adding the Bluetooth module, but then the process would be the same (or maybe even more complex, if you consider the pairing step), and it would only replace the PC with an Android phone or tablet. Using serial moni
