Arduino nano Clock

RTC clock is required in many of electronics project to show time & date on display .We can esily  make a RTC clock by arduino nano.

Components Required :

Arduino Uno board

DS1307

crystel 32.768KHz

Battery 3.3v

lcd 16x2

circuit diagram:

Arduino is a most popular controller among the hobbyist & Developers. it can be easily program and debug.Here we are designing RTC clock.RTC clock has three main components DS3231 Or DS1307 and crystel oscillator ,battery 3.3v.Lcd 16x2 is used to display Clock or time & keypad is used to set time and date.Connect all wires and components according to circuit diagram given above.

The next most important step is programming the arduino.First we have to install all required liabraries for code then Just copy paste this code on arduino ide .

Download the code Here

As you program the arduino the default time will show on lcd 16x2.we have to set current time by using keypad.
