Clock made from 7 segment display and DS3231
A simple clock made from 6x 7 Segment display and DS3231 rtc module.
First I made the prototype on an Arduino board then just to make it cleaner I just pulled the IC ( Atmega328P) off UNO and placed it on breadboard.
Added 16 MHz external oscillator and a LM2596 power regulator ( 12V to 5V ).
for more info on how to use the Makefile and compile_upload.sh refer my post on medium : https://medium.com/@swarnakar.ani24/arduino-sketches-ino-and-makefile-844db9c51d2b?source=friends_link&sk=a50ea892ae07bf27b0d358a648a49ca9
Plans for V2.0
-Clear code
-Push buttons on breadboard to set time of rtc.
-Since ds3231 supports alarm functionality explore that. May be add ESP8266 to set alarm wirelessly and sync time too.
