Brainy Circuits
Build, code & simulate Arduino projects online.
An interactive platform for learning Arduino, electronics and circuit design, entirely in your browser.
- 30+ components
- C/C++ & Blockly
- Real AVR-GCC compiler
- No hardware needed
Features
Everything you need in Brainy Circuits.
Brainy Circuits is a browser-based Arduino simulator that lets anyone design circuits, write code and test projects without physical hardware. Drag components onto a virtual breadboard, program them in C/C++ or visual Blockly blocks, and watch LEDs glow, servos rotate and displays light up in real time.
Drag-and-drop circuit builder
Assemble circuits from 30+ components, including LEDs, sensors, motors and displays, on an intuitive canvas.
Code your way
Write C/C++ in a full code editor, or snap together visual Blockly blocks that generate code automatically.
Real compiler, real behaviour
Sketches compile with the actual AVR-GCC toolchain, so what you simulate behaves like real hardware.
Virtual breadboarding
Wire it up on a realistic breadboard with color-coded jumper wires, just like on a lab bench.
Live component feedback
LEDs glow, servos rotate and displays show text as your code runs, giving instant visual feedback.
Zero install
Everything runs in the browser. Open a tab and start building on any laptop or lab computer.
How it works
Up and running in three steps.
01
Design the circuit
Drag components onto the breadboard and wire them up.
02
Write the code
Program in C/C++ or with visual Blockly blocks.
03
Simulate & iterate
Run it, watch it react, tweak and run again.
Who it's for
Made for people who use Brainy Circuits.
Students
Practice Arduino programming anywhere for coursework and self-learning. No kit required.
Educators
Teach embedded systems without managing physical lab equipment or broken components.
Makers & hobbyists
Prototype and debug designs virtually before buying a single part.
