Hello everyone, my name is Matei. Welcome back to my show and tell. Today I am excited to present my project. My project is about an RGB LED that changes colors. When the LED shows white color, a song plays using a buzzer. I used different components like code, a buzzer, an RGB LED, and a switch. The switch helps to control the system. I enjoyed building this project because it is fun to see colors change and hear music together. I hope you like my project and enjoy my presentation. Thank you for listening!
From code to campaign.
Coming Soon.
Big ideas, young voices.
Real experts. Real questions. Real answers.
Coming Soon.
I've designed and developed innovative solutions to real-world problems through these entrepreneurial projects.

Matei, 9, enthusiastically presented his Digital Dice project created with the micro:bit and MicroPython. The device replicates a traditional board-game die but works digitally — when shaken, the micro:bit’s accelerometer detects the movement, triggering random.randint(1, 6) to display a number. Each number is paired with a fun image, such as an angry face or smiley, and accompanied by music. Matei explained how he used the micro:bit Python editor to code accelerometer input, LED image display, random number generation, and sound playback. His project combined programming skills with creative outputs, showing how code can transform a small device into an interactive game tool.
I am presenting my Smart Security Alarm Project. I used a Micro:bit connected to a PIR motion sensor and an RGB LED. The Micro:bit detects motion through the sensor. When motion is sensed, the RGB LED lights up at maximum brightness in white, and a sound plays using the music module. The program uses a custom RGB function to control the LED, while a loop continuously checks the sensor.
