TITLE :THE DEVELOPMENT AND INSTALLATION OF A HOME APPLIANCES’ AC MAINS VOLTAGE FLUCTUATION INDICATOR

Abstract : Using a multimeter is currently the most practical way to measure the Root Mean Square (RMS) Voltage of a Line Power System. However, instead of using the ground pin, a multimeter uses the measuring probe as the point of contact with an electrical outlet. This could occasionally be quite dangerous. In order to address this issue, this research suggests substitute measuring tools for multimeters that can also clearly display voltage variation. The equipment should be plug-and-play during use, dynamic, accessible, and safe according to the research. The project’s equipment will use 12 LEDs as a voltage level indicator rather than the numeric display used in Multimeters, highlighting the equipment’s accessibility even more. Each of these LEDs is attached to an Arduino output pin, and each pin is configured to turn on only at a particular voltage value. The results of the tests show a dynamic voltage level indicator. The LED will instantly reflect any changes in voltage level without any discernible delay. Since no harm was caused while operating the circuit during testing, it is also quite safe. The only required action is adjusting the potentiometer, highlighting true plug-and-play. Despite its success, it has two significant weaknesses. We noticed an unexpected voltage drop between the regulator output and an Arduino input pin. Additionally, the voltage at the Arduino input fluctuates wildly downward. Ideally, the data gathered would contribute to the equipment’s improvement.
