🧩 Program your robot
Tap a block to add it. Tap a Repeat / Forever / If box to put blocks inside it.
🎮 Drive by hand
Steer the robot yourself with the stick, the arrow keys / WASD, by tilting your phone, or with a game controller. Reach the green zone to win. Space starts/stops a run.
🔧 Parts Lab: build your robot
Pick a kit, or turn on Hands-on build to assemble it yourself. Parts follow real rules: mounting, pins, voltage and power.

⚡ Breadboard Lab
A real-style breadboard: the five holes in each short column are connected, the two halves are separate, and the + and − rails run the whole length. Pick a challenge, build it, then check it.

🔊 Echo sonar
Use your phone like a bat. The speaker sends a short chirp, the microphone hears the echo, and the delay tells you the distance: distance = speed of sound × time ÷ 2. Hold the phone 15 cm to 2 m from a flat object like a wall or a book. Quiet room works best.
📷 Camera light sensor
Use your phone camera as a real light sensor. The brightness it sees controls the light sensor (LDR) in your circuit. Nothing is recorded or uploaded.
💻 Your program as real code
This is what your blocks turn into on a real robot. Copy it into the Arduino IDE or Thonny.
🔌 Build it for real
Run your program on a real Arduino robot. Download the sketch, the helper library and a parts & wiring guide.
🔗 Share your program
Copy a share code and send it to a friend or teacher. They paste it here and press Load.
🔌 Live link to a real robot
Mirror your simulated robot onto a real Arduino robot over USB. Needs Chrome or Edge on a laptop, and a robot running the Live sketch. (iPhones cannot do this.)
