Three years ago, when I started working digital electronics with microcontrollers, I was building using a liquid crystal display (LCD). The following year, I began building projects using a RTC chip. This time, I decided to rebuild what I already learned and make it work for my Arduino MiniArduino Mini.
This Fritzing drawing is only symbolic of what I built. I'm using an RTC module for the RTC circuit I've built. Though I'm using the Arduino Mini for this project, the source code can be reused for other Arduino AVR boards. Though not expressly shown in this Fritzing drawing, 5VDC power is implied. I decided to not use a breadboard in Fritzing because the major components won't fit right.
