Plant moisture sensor & Traffic light pole & Light level

Hi everyone! My name is Essa, and I’m 9 years old. My project is called Plant moisture sensor & Traffic light pole & Light level. My project uses a soil moisture sensor, a traffic light pole, and the light-level sensor on the micro. The soil moisture sensor checks how wet or dry the soil is, while the light sensor checks how bright it is. If the plant has good moisture and enough light, the micro shows a happy face and the green light turns on. If the moisture is in the middle range, it shows a sleepy face and yellow light. If the soil is too dry or the light is too low, it shows a sad face and red light.

Snap the dot 3.0

Hi everyone! My name is Esther, and my project is called Snap the dot 3.0. It is a fun reaction game where you have to press the correct button at the right time. The game uses Button A, Button B, and the A+B combination. A sprite moves across the screen, and when it reaches the correct position, you have to press the matching button. If you press the wrong button, the game is over. When you get an answer correct, you see a smiley face and continue playing. My code also uses variables, a score, movement, bouncing, and music. My favorite part is the game-over noise!

Rock,paper,scissor

I created a fun micro:bit game similar to Rock, Paper, Scissors, but with my own creative twist—Bunny, Carrot, and Gun. The micro:bit uses a “pick random 1 to 3” block to choose one of the three options and displays the matching LED image. I also used if–else conditions to make decisions and show the correct picture. I enjoyed designing the icons and coding this interactive game.
