Alert

Hi, my name is Vishvhesh. I’m 10 years old, and I’m going to fifth grade. My favorite hobby is playing cricket outside. My project is called the Alert . It is designed to alert a robot when it needs to take action. I used a Raspberry Pi Pico, buzzer, slide switch, RGB LED, 220-ohm resistor, and male-to-male jumper wires. When the slide switch is off, the RGB LED glows green, meaning everything is safe. When the switch is turned on, the buzzer makes a sound and the LED turns red. This creates an alert signal for the robot. I used Python code to control everything.

Name Badge

My project is called Name Badge. I made it using the Micro:bit to display fun facts about myself in a creative way. The Micro:bit picks a random number between 1 and 3, and each number shows something different about me. One shows a happy face and my name, two shows a chessboard and my favorite food (chicken), and three shows a Pac-Man icon and my favorite game (Roblox). I

Vishvhesh, a games enthusiast (Roblox, Abduction board game, Garbage cards, badminton), presents his micro:bit "Dice" project. Shake the accelerometer for random.randint(1,6)—displays number + matching image: 1=angry, 2=sad, 4=smile, 5=fabulous, 6=happy. sleep paces rolls. Perfect for settling arguments (2-6 people; edit for more). Demo shakes yield 6 (happy), 2 (sad), 5 (fabulous), mimicking real dice. Accelerometer adds authentic "roll" feel—ideal board game substitute!

Joystick rover

Hello everyone! My name is Vishvhesh Kaliappan , and I am excited to present my project. I am passionate about electronics and programming, and my journey with Moonpreneur has helped me improve my skills. My project is a joystick-controlled rover using two micro, a joystick, and a breakout board. The joystick controls the rover’s movement. When I move it forward, backward, left, or right, the rover moves in that direction. The project uses different speed values for forward, backward, and turning. The micro also show letters such as F, B, L, R, and S to show the rover’s movement.
