Multifunctional Microcontroller Based PC and Smart Phone Operated Digital IC Companion

In this paper, a smart multi-controlled (both phone and PC) multifunctional digital IC monitoring system has been introduced. This paper focuses on developing a cheaper and lighter but more efficient IC checker system with advanced features. The system allows the flexibility to use both wired (USB serial communication) and wireless (Bluetooth SPI communication) medium. The system proposes 5 different operational mode. The prototype enables the user to easily interface with the controller to check, detect ICs or to make any type of makeshift IC. Moreover new ICs also can be added to the system conveniently. Different frequently used ICs such as logic gates, flip-flops, multiplexers, counters of 74XX and 40XX series can be tested, detected or similar functions created practically using the prototype. Logical comparison and analysis is the base formula of the proposed prototype. The proposed research work is implemented practically to observe all the objectives of the prototype with a core Arduino microcontroller unit of ATmega328 which by default comes with an USB interface. The processing latency of the prototype is faster about 1.33 times and almost 5 times cheaper comparing with present market devices, in terms of TTL IC testing. The proposed system is perfected to be reliable in accuracy for both industrial and laboratory applications.
