Circuvo: Arduino Simulator

Turn your iPad into a complete Arduino lab. Circuvo lets you build electronic circuits, wire up a breadboard and program them with easy drag-and-drop blocks — then press Run and watch everything come to life in a real-time simulation. No hardware, no wiring mistakes, nothing to buy.

Whether you're a curious beginner, a student or a maker, Circuvo makes learning electronics and coding genuinely fun.

WHY CIRCUVO
• Visual block coding — snap blocks together, no typing required
• See the real Arduino (C/C++) code your blocks generate
• Live circuit simulator — LEDs glow, buzzers sound, motors spin, sensors react
• A full parts bin: LED, RGB LED, push buttons, potentiometer, buzzer, servo, LCD screen, ultrasonic distance sensor, PIR motion, light sensor (LDR), temperature sensor, joystick, relay and more
• Breadboard wiring and a Serial Monitor, just like the real thing

LEARN STEP BY STEP
• Guided, hands-on lessons from "What is Arduino?" to full projects
• Tracks for Concepts, Basics, Breadboard, Sensors and Projects
• Interactive quizzes and "now you try" challenges
• Earn badges, build streaks and track your progress
• Ready-made demo projects: traffic light, night light, parking sensor and more

MADE FOR EVERYONE
• Perfect for kids, teens, students, teachers and self-learners
• Great for STEM and coding classrooms and homeschooling
• 6 languages, light & dark mode
• Works offline · No account needed ·

Start with a single blinking LED and work your way up to real, sensor-driven projects — all from your pocket. Download Circuvo and start building today.
