01 Circuit
A board that can fail like a real one
Most simulators show what the code does.
You draw every wire
Drop a part on the canvas, drag pin to pin.
Every wire belongs to a pin.
Real compiler, real errors
On the desktop the sketch is built with the actual Arduino toolchain.
In the browser a built-in interpreter starts instantly.
Uno, Mega, Nano, ESP32

02 Academy
From the first LED to a keypad matrix
Every topic has three levels.
The checker is not fooled
Printing “LED on” proves nothing.
