Circuit Documentation
Summary
The circuit in question appears to be designed to control an AC LED bulb and a buzzer using an IR sensor and a 5V relay. The IR sensor detects the presence of an object or motion and triggers the relay, which in turn switches on the LED bulb and the buzzer. The circuit is powered by a 5V adapter and a 9V battery. The 5V adapter supplies power to the IR sensor and the relay, while the 9V battery is used to power the LED bulb and the buzzer through the relay.
