Design and Implementation of a 4-Bit Breadboard CPU Using Digital Integrated Circuits
Abstract: This paper presents the design and hardware realization of a simple 4-bit CPU built using discrete TTL integrated circuits on a breadboard. The CPU employs a 4-bit common data bus with tri-state buffers for device arbitration, three 4-bit registers (Register A, Register B, and an Output Register) implemented with 74LS175 quad D flip-flops, and a 4-bit ALU for addition/subtraction using a 74LS83 adder and XOR gates. Manual control signals (load, …

Smart Cardiazmo Implemented Using Internet of Things
Abstract: In this research, we present a system that uses sensors to identify a person's heart rate utilizing heartbeat sensing even if they are at home. The idea is to detect a heart attack early enough that the patient can receive medical help within the first few hours. As a result, his or her chances of survival are considerably increased. Here we use the AD8232 sensor for the cardiography of the …

Development of a Cost-Effective Automatic Power Transfer Switch for Backup Energy Systems
Abstract: This study offers a practical solution to the frequent power outages in places like Nigeria, where having backup power sources, such as inverters, is crucial. To make switching between the main power supply and backup power easier, the authors created a simple but effective transfer switch. The design uses important components like an electromechanical relay, a contactor, a voltage monitoring relay, and delay timer relays to ensure smooth switching between …
