Breadboarding
The virtual breadboard is your canvas. In Intarva, breadboarding follows real-world physics, meaning incorrect rail connections can lead to simulation conflicts.
1. Power Rails
The long vertical strips on the edges of the breadboard are Power Rails. In the Intarva Editor, these are typically used to distribute a common voltage (like 3.3V or 5V) and Ground across your entire circuit.
2. Terminal Strips & Continuity
The main area of the breadboard consists of Terminal Strips. Each row of 5 holes is internally connected. In Intarva, if you place two component pins in the same row, they are automatically merged into a single electrical Net.
The Center Divider
The notch running down the middle of the breadboard physically separates the left and right terminal strips. This allows you to “straddle” Integrated Circuits (ICs) like the 74HC595 without shorting their pins together.
3. Best Practices for Virtual Wiring
- Color Coding: Use Red for VCC and Black/Blue for GND to make your circuit instantly readable.
- Avoid “Bird’s Nests”: Use short, right-angle wires to keep the simulation visually clean.
- Isolate High Current: If you are using motors, use a separate power module to avoid “Noise” in your microcontroller’s logic.
