A block diagram is shown below to understand the working of this Real Time Clock.Īs you can see in the circuit diagram, DS1307 chip pin SDA and SCL are connected to arduino pins SDA and SCL with pull up resistor that holds default value HIGH at data and clock lines. A buzzer is also used for alarm indication, which beeps when alarm is activated. DS1307 sends time/date using 2 lines to arduino. Here arduino is used for reading time from ds1307 and display it on 16×2 LCD.

DIGITAL ALARM CLOCK MINI PROJECT PRO

In this Arduino based digital clock circuit, we have used three major components which are IC DS1307, Arduino Pro Mini Board and 16×2 LCD module. Steps for data reading from slave to master (slave transmitting mode)

And last sends STOP condition to slave.

Steps for data writing master to slave (slave receiving mode) Most of I2C devices run on100Khz frequency. It can be used to communicate 127 devices to a single device or processor. I2C protocol is a method to connect two or more devices using two wires to a single system, and so this protocol is also called as two wire protocol. Real time clocks are commonly used in our computers, houses, offices and electronics device for keeping them updated with real time. Once alarm time it saved in internal EEPROM of arduino, it remains saved even after reset or electricity failure. An Alarm option is also added and we can set up the alarm time. In this project we have used a 16×2 LCD module to display the time in – (hour, minute, seconds, date, month and year) format. When power is reconnected, it displays the real time irespective to the time and duration it was in off state.

Real time clock means it runs even after power failure. This Arduino based Real time clock is a digital clock to display real time using a RTC IC DS1307 which works on I2C protocol. Arduino Tutorial Online Courses Video Training.

Now run the “file.py” file using the following command: python file.pyĪfter the successful run, you will see something like this on-screen. The font size of the clock string is set to 40 and I added vertical padding of 150.

Style the clock widget to make it attractive.

I added a footer label on the window screen too.

After that, set a title for the window screen. Here the dimension of the window screen is 500x500. To retrieve the system’s time, import strftime function.

You can install it manually too.įile.py from tkinter import * from time import strftime root = Tk() root.geometry("500x500") root.resizable(0,0) root.title('Python Clock') Label(root,text = 'YOUTUBE - BUG NINZA', font ='arial 20 bold').pack(side=BOTTOM) def time(): string = strftime('%H:%M:%S %p') nfig(text = string) mark.after(1000, time) mark = Label(root, font = ('calibri', 40, 'bold'), pady=150, foreground = 'black') mark.pack(anchor = 'center') time() mainloop() If you are a windows user then, you can install Tkinter at the time of Python installation. To install Tkinter in Linux, you can use the command as shown below. Tkinter is a Python package that mainly deals with the GUI part of a Python project. To use the “tk” library, you must have Tkinter installed in your system.

Now, make a python file inside this “clock” directory and name it as the file.py.

But make sure that the virtual environment is installed in your system. If you are a Windows user then make a virtual environment using the following command. Virtualenv -p python3.8 clock cd clock source bin/activate

If you are a Linux user, then make a virtual environment using the following command.

As you know, making a Python project in a virtual environment is a good habit.
