Weekly Progress
Overall: Last weekend I bought IC DS1307 that is a real time clock memory. I learned and tried to write the
programming about the expiration date of product.
Engineering Knowledge: Base IC DS1307 is a time danlat employs (Dallas Semiconductor) is a bus transport, which
is a 2 wire I2C communicate 2 directions (bidirectional bus). Base of the DS1307 can store information on hours,
minutes, seconds, date, month and year. The system time can work 24 hours format mode or 12 hour AM/PM time
within the system detected the power supply if the primary power supply is cut off to switch to using power from
the DS1307 can battery and continue running where you can maintain all the pins structure has 8 legs. Chassis I2C
(Inter-IC Communication) form has been developed by filip (Phillips). Transportation used 2 lines, the data signal
cable (Serial Data line) SDA and SCL clock signal cable (Serial Clock line). IT ‘s working as a Master and Slave device
that serves as the Master (microcontrollers) will control the flow of data and control signals clock on SCL Slave
device (DS1307) section will work under the supervision of the Master device. Continue working with
microcontrollers with I2C bus system can be done by per resistor Pull up in cases that require multiple Slave
devices connected together with a Slave device by parallel to communication between the Master and each Slave
device. IT can be split by the Slave Address of the device that will be sent from the Master device to device Slave
before starting the transport.

Strong Point:
- It's precision work.
Weak Point :
- It's only time. If there is no
power at all times it will
forget that count.
Next Week Job
I will done the programming and make to perform devices
