ARDUINO NANO || 20X4 LCD || DS3231 temperature Sensor || DHT11 humidity Sensor
This is arduino based digital clock. A real time clock (RTC)
module named DS3231 is used for controlling the time, day, date. This clock module
has an internal battery backup system. Here used a humidity sensor named DHT11, to
sense humidity. one 20X4 lcd is used for displaying the all data. This clock has some
special fetures such as
1. it shows special date of calender
2. it has hourly alert
3. it can detect temperature
4. it can detect humidity
5. it has colour alert of temperature, special date by an RGB LED
