Use the + and - keys on your numeric keypad, or right-click, to rotate or mirror the component before placing it. Click a second time to lock the component onto the grid. Wiring the Components Proteus utilizes an intelligent autorouter for schematics:

Click the Track Mode icon, select your desired trace width (e.g., T20 or T30 ), click on a pad, and follow the yellow ratsnest line to complete the trace.

What are you trying to build? (e.g., an Arduino project, an audio amplifier, a power supply)

Review the summary and click Finish to open the workspace. 3. Step 2: Schematic Capture (Designing Your Circuit)

Always run a Design Rule Check (DRC) in ARES before exporting your files. This highlights any short circuits, overlapping lines, or traces that are too close together.

Ideal for visualizing time-domain waveforms (e.g., clock signals, audio waves).

Use your mouse to rotate, pan, and zoom in on the board. This allows you to check component orientations, spacing, and ensure that no structural components overlap. Best Practices for Proteus 8 Users

Select layer (usually blue) for a standard single-sided through-hole PCB.

One of Proteus's strongest features is its interactive SPICE simulation engine, which allows you to test circuit functionality before ordering physical parts. Utilizing Virtual Instruments

Which are you planning to simulate (e.g., Arduino, PIC, STM32)?

Click the target pin when the green square reappears to complete the connection.

Connect an external LED and a 220-ohm resistor to digital of the Arduino.
