Open sandbox mode
Jump directly to free-form breadboarding without waiting through beginner story gates once your account is active.
FOR HOBBYISTS & HARDWARE FANS
Validate circuit ideas fast before touching iron to board
Whether you are building a solar charger, smart home relay, or your first Arduino project, iterate cleanly in the open sandbox and pair with physical parts.
Component confidence
Check resistor values, sensor wiring, and AVR compilation output in seconds before wiring real components on your bench.
Physical kits ready
Start with the Arduino Explorer Kit assembled in Lagos and reuse offline project blueprints anywhere you build.
