Placing components

Click Add in the toolbar (or the + button on the canvas) to open the component picker:

• Search by name or function: oled, dht, resistor, servo…
• Filter by category with the dropdown on the right — boards, displays, sensors, motors, logic, analog parts, and branded modules.
• Cards with a PRO badge need a paid plan to run — you can see the whole catalog regardless. See plans.

Click a card and the part lands on the canvas. From there:

• Drag it to position it.
• Click to select (a dashed marquee shows the selection).
• Right-click for the part inspector — properties, pinout, datasheet, rotate and delete.
• Delete or Backspace removes the selected part.

Every part on the canvas is live during simulation: LEDs light, displays draw, buttons click, sensors report the values you set on them.

The full catalog, with a page per part, is in the parts reference.
