Voice Activated Switch Kit

Voice Activated Switch Kit – Sound‑Responsive Circuit Project for Electronics Learning

The Voice Activated Switch Kit is an engaging, self‑assembly electronics project that introduces students to sound‑triggered switching. The circuit activates when it detects a noise or voice input, with both adjustable sensitivity and a 1–60 second delay timer for custom control.

Supplied with full instructions and requiring a 12V DC supply, it is ideal for practical electronics lessons focused on inputs, sensors and timing circuits.
