<![CDATA[A This study aims to design and analyze a prototype lamp that can be controlled using voice commands as an application of Ohm's Law in a simple electronic circuit. This system utilizes the LM393 sound sensor module as input to activate and deactivate LED lights without physical contact. The method used is descriptive quantitative with direct measurements of voltage (V), current (I), and resistance (R) on five types of LEDs. The measurement results show that the yellow LED has a voltage of 2.0 V, a current of 0.48 A, and a resistance of 4.1 Ω; red 2.2 V, 0.46 A, 4.7 Ω; orange and blue 2.8 V, 0.42 A, 6.6 Ω; and green 3.0 V, 0.42 A, 7.1 Ω. The system shows an average response time of ±1 second following voice input at a distance of 1.5 m. These results indicate a linear relationship between voltage and current in accordance with Ohm's Law (V = I × R) and the effectiveness of the voice control system. This research confirms that basic physics principles can be integrated into simple smart technologies to support project-based physics learning]]>
