About

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!

Digital Dice

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.
