PCF8583 is frequency divider, he gets clock ~32kHZ from xtal, and just divide to get signal 0.1Hz. Accuracy of PCF8583 is accuracy of xtal.
What we need in this circuit is the only basic components required for any microcontroller based circuit.
The Basic component is Microcontroller based Project
The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature.
PIC 16f877 have built in six adc of 10 bit resolutions. So no worry of using any external adc in this project. we will use one of them for analog to digital conversion. Lm35 .

How to Program the Microcontroller?
All the things you need for using microcontroller are the basic tools required for setup of microcontroller Lab.
To program the Microcontroller you just need to do 3 things:
1. write the program using an integrated development environment like MIGCC.exe
2. compile the text using a compiler program
3. download the compiled program into a chip
Benefits of Using Microcontrollers :-
The microcontroller because of its versatility, ease of use and cost will change the way electronic circuits are designed and will enable projects to be built which previously would have been too complex.
What can the microcontroller measures?
Microcontroller can measure all physical quantities which are measured by other methods or mean like Temperature, light, magnetic, electrical, sound, distance, velocity. But you need proper transducer to convert that physical quantity to electrical energy.
What is PICFUN?
PicFun is used by all Australian Secondary schools as part of their technical education. PicFun is a programmer developed by Australian company using PIC microcontroller.
PICFun Programmer and Controller:-
For Educational and Professional Applications PICFun is a kit designed as a request from high school teachers to provide an easy way to teach microcontroller programming. The students are able to construct a useful project on the actual circuit board they are using to program the PIC chip! In effect they can program and reprogram the PIC microcontroller for endless possible applications of their choice, all without taking the
microcontroller off the board because the PIC chip has FLASH MEMORY which makes it electrically erasable.
Example of use of PICFUN:
Industrial Application by High School students. They automated the assembly of the three separate parts (plastic handle, metal clip and bracket) which make up the detachable handle of a grill pan on an electric oven. The machine assembles a handle in just 25 seconds.
The objective of the new approach was achieved although there were problems encountered. Students needed to improve their skills in the C-programming language and connecting skills as the micro-controller was rather small in size. Despite the problems, students like to use this micro-controller as they could see the output of their hard work. The staff derived greater satisfaction when students learned and achieved the objectives of their lessons. Students were able to understand and achieve the end results of their programming techniques and experiment results.
