Activity : Research about the component that will uses in the project

Objective:

• To study about the microcontroller AT89S52
• To study about the peristaltic pump using stepper motor
• To study about the dialyser

Content/Procedure:

1. AT89S52 is use in this project as microcontroller that will control all the process of the system.
2. Peristaltic pump using stepper motor to transporting the blood from the input to the output. 
3. water filter is use to replace dialyser in this project

Result/ analysis:

1. AT89S52 is 8K byte programmable flash memory
2. AT89S52 have 4 ports , 2 interrupts,3 timers and etc 
3. Stepper motor using unipolar mode
