How do I…?
The short version
Pick parts. Every part on the shelf is a real electronics component. Click to place or drag onto the mat.Tap a part and it lands on the mat. Its name sits under it on the bench; select it to see what each pin is called, or rest the mouse on it for what it does and how to wire it.
Wire them. Drag from one pin to another. The pin turns gold when you are over it. Pins on the same breadboard strip are already connected (hover a hole to see its strip). Small parts too small to see next to the Uno? Select one and use the bigger / smaller buttons above the bench. Each part has its own size.
Run. Press Run. LEDs glow, motors spin, buzzers beep and mistakes show up as smoke or a warning. Every part shows its reading right under it on the bench (current, volts, angle, "no power") and every wired pin shows its voltage. Nothing on this bench can actually break, and that's the point.
Code it. Select a board and open Code. It's real Arduino C++: pinMode, digitalWrite, Serial.println, Servo, LiquidCrystal_I2C and more. Each part's Learn tab has a wiring guide and a ready example.
