ELECTRONICS COMPONENTS TESTER
[attachment=53123]
INTRODUCTION
This Project Components tester can be used to check the
electronic components such us Diode, Transistor, Capacitor,
IC555, IC741 and Continuity. The whole circuit was controlled
by the Microcontroller AT89C52. The circuit has an LCD
display it was used to display the Text messages over it. The
system will display the conditions of the device on the LCD
display. The Microcontroller used in this project was an 8 bit
microcontroller AT89C52 it has a program memory of 8
Kilobytes. For checking the IC555 an external circuit was
configured as astable multivibrator and for checking IC741 an
external circuit was connected as a comparator. The
microcontroller will check the output and display it over the
LCD.
