Summary of the Circuit

This circuit is designed around the Arduino UNO microcontroller and includes a set of peripheral components that interact with the microcontroller. The peripherals include a KY-026 Flame Sensor for detecting flames or fire, a buzzer for audible alerts, an LED with a current-limiting resistor, and the necessary power connections. The Arduino UNO controls the buzzer and receives input from the flame sensor, while the LED serves as an indicator. The circuit is powered by the Arduino's 5V output, and ground connections are shared among the components.
