Circuit Documentation

Summary

This circuit consists of an IR sensor, a buzzer, and a 9V battery. The IR sensor detects an object and triggers the buzzer to sound an alarm. The circuit is powered by a 9V battery.

Component List

1. IR Sensor

   • Pins: out, gnd, vcc
   • Description: Detects infrared light and outputs a signal when an object is detected.
   • Purpose in Circuit: To detect objects and send a signal to the buzzer.

2. Buzzer

   • Pins: PIN, GND
   • Description: Emits sound when a signal is received.
   • Purpose in Circuit: To sound an alarm when triggered by the IR sensor.

3. 9V Battery

   • Pins: -, +
   • Description: Provides power to the circuit.
   • Purpose in Circuit: To supply the necessary voltage to the IR sensor and buzzer.
