Wires, sensors, small miracles.

Every LED that blinks is a tiny victory. Here are the Arduino builds where electricity learned to listen.

The Waving Cat — code turned into a friendly hello.

Built on a Be Cre8v Arduino board — the brain of the project. I programmed it in Snap4Arduino using colourful blocks: a forever loop that sweeps a servo motor back and forth. When I hit the green flag, the signal travels down the wire and the little cat lifts its paw and waves.

Snap4Arduino blocks: a forever loop toggling the servo between 10° and 50°.

  • 🧠Brain: Be Cre8v Arduino board (Arduino Nano inside).
  • 🧩Language: Snap4Arduino — visual, block-based coding.
  • ⚙️Hardware: a servo motor wired to pin D9 for the waving paw.
  • 🔁Logic: a forever loop toggling the servo between 10° and 50° every 0.2s.
  • 👋Result: a friendly cat that waves the moment I press the green flag.
Featured Project · Game Controller

Car Park Challenge — a steering wheel wired to my code.

I turned the Be Cre8v board into a real game controller. A purple steering wheel spins the car in circles, and the left and right arrow keys guide it through a crowded car park. The mission: reach the pink parking bay without bumping into any other cars — or the trees near the entrance. One touch and it's game over. A clean park, and you win.

Almost there — lining up with the empty bay between the red and white cars.
Snap4Arduino script: arrow keys move the sprite, touch-detection ends the game.
