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)”
