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.

Smart security alarm

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.

Raspberry pi pico with a buzzer & Led

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!

Moon-rover with garage

Hello everyone and welcome back to my show and tell event. Today I am excited to present my project. I wanted to create a toy car that can be controlled using a joystick. This idea inspired me to build a mini rover using technology. In my project, I used a joystick and a micro to control the movement of the rover. The joystick helps me move the car forward, backward, and turn. I really enjoyed building and testing this project. It helped me learn how hardware and coding work together. I hope you like my project. Thank you!
