Week 4 FYP 2

List of activity

Study about RTC

Objective

To make RTC circuit

Content

After make some research i had found a suitable RTC with arduino.This module has the integrated time keeping system using a crystal oscillator. So the timing is accurate with multiple applications. This module also has a battery backup with which the module can keep track of the time even when the Arduino is programmed or turned off. Lets start off with the stuff you will learn and the applications of this module. Apart from the arduino the DS1307 Integrated Circuit is the core of this project since it acts as the timekeeper and tells the arduino when it should leave the appliance on. The DS 1307 is specifically designed for timekeeping, The time is fairly accurate with an error (time drift) of about 1 minute per month.The beauty of the DS1307 is that it has this backup coin cell. This Coin Cell is commonly the CR2032. This battery is more than enough for the IC since the DS1307 has a fairly low power consumption the backup battery life of the cell is about a minimum of 9 years of usage.The DS 1307 communicates with the arduino using I²C communication. Simply put the chip sends data in decimal form such that each decimal form is 4 bits of binary data also known as Binary Coded Decimal System.

Figure above show the simulation circuit for RTC circuit that i have done by using Proteus software
