This project uses an Arduino UNO, a relay module, and an electret microphone amplifier to create a voice-activated smart light system. The microphone detects sound, which the Arduino processes to control the relay, turning a 220V bulb on or off. Students across India are building similar projects for science fairs, college submissions, and personal use. A kit is available from our partner Home Science. Turn Your Voice into Magic: Control LEDs with Simple Voice Commands! Ever wanted to feel like a wizard, controlling lights with just a word? With our Bluetooth Project, you can do just that! This exciting and straight forward tutorial will show you how to control an LED using voice commands, all. Complete the assembly of the voice-controlled light, master the assembly and connection methods of the light module, lamp holder structure, and voice recognition sensor, and realize the control of the light's on/off, brightness adjustment, and color switching (if using a color light) through voice. Controlling electronics with voice commands is one of the most exciting applications of IoT and embedded systems.
