Microprocessor Controlled 16 Line Connectivity Tester
This is an ATmega32 based Proteus simulation of 16 line connectivity tester. I mainly did this project to get familiar with the new
8 simulator (mainly the new Proteus - ISIS module).
The main functionality of this system is to detect open and short circuits in cables and connectors. This system can test maximum of 16 lines in each test cycle and it indicate the defective line(s) through LCD. This is customizable system and user can configure number of test lines through single push button (SW1).
The ATmega32 firmware is developed using
tool-set and it design to work with both simulation and real modes.
I never test this system with real parts. If someone interested about real implementation make sure to change RN1 and RN2 to 22K and diode array with 16 - 1N4148 diodes. Recommended supply voltage for this system is 5V DC.
