Differential Counter Design with Voice Output and Storage on SD Card

Differential counter is a tool used to calculate the type of white blood cell. Observation of the results of white blood cell count can provide more specific information about infection and disease progression process. The main basis in calculating the type of white blood cell is the calculation using standard (standard) tools. This design is based on ATMEGA 8535 which uses 6 push buttons to represent each type of white blood cells to be counted and 1 push buttons to reduce what if there is an excess in the calculation. This module also uses ISD 2560 to store the cell sounds to be counted. It is further processed by ATMEGA 8535 microcontroller and displayed on lcd and can be stored on SD Card. The purpose of this research is to design the Differential Counter Equipped With Sound Output And Storage In SD Card. The research design used is pure experimental research that is independent variable is white blood cell type. The phases used are circuit design, and test.
