Adjusting clock with alarm & thermometer using DS3231 on 1.8" ST7735 display

   In previous article I made a clock with manual adjust for date and hour, noow I put a push button for activate and deactivate alarm, also in menu I can change hour and minute for alarm.
   When alarm is activated a small sign and hour for alamr is with whilte
when alarm is deactivated sign and hour is with blue colour.
    When is time alarm (1 minute), if alarm is activate sign is red and LED is lit (instead led you can put a relay module for power a radio, a bulb light, etc)
but if you push ALARM button alarm is deactivade
   Schematic for made this clock is
and the sketch is TFT_DigitalClock_RTC1d.ino.
   I made a movie named adjuting clock with alarm & thermometer using DS3231 on 1.8" ST7735 display when you can see who the clock work:

   PS: I made some changes in last sketch to store hour and state of alarm in EEPROM memory of ATmega, see TFT_DigitalClock_RTC1e.ino !!!

    1. who needs in sketch
      #include // https://github.com/Bodmer/TFT_ST7735
      #include // exist in Arduino IDE
      #include "EEPROM.h" // if you not have see https://github.com/arduino/Arduino/tree/master/hardware/arduino/avr/libraries

    1. you need have RTClib library... I think I use from https://github.com/adafruit/RTClib
      test

    1. clear.. you need Adafruit_GFX library :)))))
      please first learn with easy projects as blinking led...

  11. Could this project be transferred to the Atmega 328 DIP and if so how?Video:https://www.youtube.com/watch?v=7EGG4osSZDI

    1. of course, see ATmega328 pin mapping - https://www.arduino.cc/en/Hacking/PinMapping168 - and minimal circuit - https://www.open-electronics.org/arduino-isp-in-system-programming-and-stand-alone-circuits/

  12. The project with Atmega328 is ready. On pins 9 and 10 I put quartz 16 megahertz.As such will work well scheme or I need to put another and if so from how many megahertz Video:https://www.youtube.com/watch?v=zewfz6hmOpg
