Arduino LifeClock

In this instructable we will build a unique decoration, which is capable of displaying your current age in days or weeks on a small 4 digit 7 segment display. The whole project is based around an Arduino Pro Mini inside of a picture frame of your choice.

Electronics:

Arduino Pro Mini 5V (or any other arduino with >= 12 GPIO Pins)
4 Digit 7 Segment Display
DS3231 Real Time Clock Module
4x 200 Ohm Resistors
Materials:

Picture Frame
Perf Board (matching size)
MicroUSB Breakout (or any other 5-12V power source)
Wires/Hardwires
Pin Headers (male, female)
Tools:

Soldering Iron
FTDI Programmer (in case of a pro mini)”
