Digital clock ds1307 using PIC microcontroller

igital clock using ds1307 and pic16f877a microcontroller is designed in this project. Digital clock using ds1307 displays time and date on LCD. PIC16F877A microcontroller is used to design digital clock. I2C communication protocol is used to read time and date from digital clock ds1307. PIC16F877A microcontroller is interfaced with LCD to display time and date. Digital clock ds107 use I2C serial communicati ...

A Real Time Clock IC (DS1307) project using the PIC micro.

Making A Real Time Clock (RTC) is simple if you use a helper chip such as a DS1307 because you do not need to keep track of the length of each month or account for leap years. It is all done for you, plus you get the benefit of a battery back up system that means it won't lose the data or time when you turn off main power. This PIC project uses an I2C (or IIC) Real Time Clock IC (DS1307) and a four digit se ...

Interfacing of PIC16F84A with DS1307 (RTC) code and Proteus simulation

This post provides the code for interfacing DS1307 RTC with PIC16F84A microcontroller. This DS1307 RTC has i2c based interface and PIC16F84A doesn't have any built in i2c modules, so software i2c module is created in the code. This code is written in C language using MPLAB with HI-TECH C compiler. You can download this code from the 'Downloads' section at the bottom of this page. It is assumed that you know ...

Interfacing DS1307 RTC Chip with AVR Microcontroller

Real Time Clocks, as the name suggests are clock modules. They are available as integrated circuits (ICs) and manages timing like a clock. Some RTC ICs also manages date like a calendar. The main advantage is that they have a system of battery backup which keeps the clock/ca lender running even in case of power failure. A very small current is required for keeping the RTC alive. This in most case is provide ...

Interfacing DS1307 Real time clock with PIC16f877

In any advance project we need real time clock synchronize with our work and for this purpose the best option is DS1307 (RTC Ic). Interfacing DS1307 Real time clock with PIC16f877 is done by I2C communication. To know I2C protocol you may refer my previous post “Interfacing external EEPROM with PIC Microcontroller”.  To know about Interfacing DS1307 Real time clock with PIC16f877, we should know something a ...

A Simple Clock using DS1307 and PIC16F877A

Even I have posted about "DS1307 + PIC16F877A", I didn't have chance to make a real prototype of the clock. I have done only on the simulation software. Today, I have received a comment about that post. ah_bear followed my code and schematic on that post but the clock didn't work. This is because the code on that post is for reading time from DS1307 so there must be some values in the DS1307 before you can ...
