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

   I use some schematic as in previous article  but is different sketch.

   I adapted original sketch from educ8s.tv to use manual adjustment for date and hour, alarm. Also, I remove RTC library and use subroutines for set and read data and hour, for read inside temperature of DS3231, alse I stored in EEPROM memory hour, minute and state of alarm.

  Last sketch is educ8stv_rtctft160_alarm_eeprom.ino with all features. Also state of alarm is shown by colour of alarm value and sign:

- alarm is waiting (activated)

- alarm is off (deactivated)

- alarm is on 

   You can see how work tthis version of the clock with alarm, hour & data adjustment in movie named another adjusting clock with alarm & thermometer using DS3231 on 1.8" ST7735 display
