Circuit Documentation
Summary
The circuit in question is a simple sensor-actuator system that consists of an infrared (IR) sensor, a piezo speaker, and a power source provided by a 2 x AA battery mount. The IR sensor detects the presence of an object or motion, and upon detection, it triggers the piezo speaker to emit a sound. The circuit does not include a microcontroller or any embedded code, indicating that the IR sensor directly drives the piezo speaker.
Component List
2 x AA Battery Mount
- Description: A battery mount for holding two AA batteries.
