Arduino Based Digital IC Tester Using MATLAB                             Testing of digital electronic systems generally involves applying a set of test stimuli to inputs of the device-under-test (DUT) and analysing responses of the system using a response analyser. If the DUT generates correct output responses (also called the golden response) for all the input stimuli, the DUT is regarded as fault-free. Those DUTs that fail to meet the golden response are regarded as faulty or defective. Block diagram for testing a device is shown in Fig. 1. Fig. 1: Block diagram for testing a device This project describes testing of 74xx series digital ICs using a MATLAB graphical user interface (GUI) drop-down menu based approach. MATLAB acts as the test stimuli generator to the IC, which is the DUT. The GUI initiates communication with the Arduino and provides a user-friendly and interactive approach to conduct the test. The MATLAB source program (ic_tester.m) acts as the respo
