software and hardware of multimeter

Through this project, I demonstrated strong hardware skills—including circuit design (Multisim), component selection (shunt resistors, voltage dividers), and Arduino prototyping—along with software proficiency in writing efficient, well-commented code (Arduino IDE) for analog sensor interfacing, ADC calibration, and real-time data display. My ability to simulate, build, and program a functional multi-meter highlights my hands-on expertise in embedded systems from concept to execution. The device itself, built using Arduino, measures voltage, current, and amperage by leveraging analog inputs with a voltage divider for voltage measurement and a shunt resistor for current sensing. Readings are displayed on an LCD/serial monitor, offering accurate, real-time data—a compact, cost-effective solution that showcases Arduino’s versatility for DIY electronics and circuit troubleshooting
