<\/p>\nIn this project, participants learn how to use a microcontroller (e.g., ATMEGA328P) to control an LED strip and a buzzer. Step by step, they are introduced to programming basics, controlling RGB LEDs with pulse-width modulation (PWM), and playing melodies through the buzzer. The project culminates in combining LED colors and music to create an interactive experience that excites both tech enthusiasts and audio lovers.<\/p>\n
The target audience is around 14 years old.<\/p>\n
<\/p>\n
This project combines controlling an WS2812 RGB LED strip and a buzzer. In three stages, you'll learn how to use digital pins and PWM to create visual and acoustic effects. Ideal for young tech enthusiasts, the project offers a practical introduction to microcontrollers and electronics.<\/p>\n
