I created a Flashing LED with Buzzer system using an Arduino Uno and an ELB board. This project combines visual and auditory signals to create an engaging sequence where LEDs light up one by one while the buzzer frequency increases. It demonstrates how simple components like LEDs and buzzers can be programmed to work together in a structured and dynamic way.

The system starts with a buzzer frequency of 500 Hz. After one second, the first LED turns on, and the buzzer frequency increases to 600 Hz. This pattern continues, with each new LED turning on while the frequency increases by 100 Hz, until the eighth LED is lit and the buzzer reaches 1200 Hz. Once all LEDs are on, the system resets, turning off all LEDs and returning the buzzer frequency to 500 Hz, creating a looping effect.

This project can be expanded in multiple ways. By adjusting the speed, frequency range, or LED sequence, the system could be customized for different uses, such as an alert system or a countdown timer. It could also be integrated with sensors to trigger the lights and sounds based on external inputs. With further development, this flashing LED and buzzer system could serve as a fun and functional addition to various real-world applications.
