Schematic editor interface in PCB Design - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to add a new component to the schematic.

PCB Design

schematic.add_component([1])

Drag options to blanks, or click blank then click option'

Arotate

Bdelete

Czoom_in

Dresistor

💡 Hint

Common Mistakes

Using actions like delete or zoom instead of a component type.

Passing a command instead of a component name.

The add_component function requires the component type to add it to the schematic. Here, resistor is the correct component to add.

2fill in blank

medium

Complete the code to connect two components with a wire.

PCB Design

schematic.connect([1], component_b)

Drag options to blanks, or click blank then click option'

Acomponent_a

Bdelete_wire

Czoom_out

Drotate_component

💡 Hint

Common Mistakes

Using commands instead of component names.

Confusing the order of arguments.

The connect function links two components. The first argument should be the first component, here component_a.

3fill in blank

hard

Fix the error in the code to select a component by its ID.

PCB Design

selected = schematic.select_component([1])

Drag options to blanks, or click blank then click option'

Acomponent_id

B'1234'

C1234

DNone

💡 Hint

Common Mistakes

Passing the ID as a number without quotes.

Using undefined variables.

The component ID should be passed as a string, so it must be enclosed in quotes like '1234'.

4fill in blank

hard

Fill both blanks to create a dictionary of component names and their positions.

PCB Design

positions = { [1]: schematic.get_position([2]) for [1] in components }

Drag options to blanks, or click blank then click option'

Aname

Bcomponent

Ccomp

Dpos

Attempts:

3 left

💡 Hint

Common Mistakes

Using different variable names for key and argument.

Using variable names that don't match the iteration.

We use the variable name to iterate over components and get each component's position by passing name to get_position.

5fill in blank

hard

Fill all three blanks to filter components by type and create a list of their IDs.

PCB Design

filtered_ids = [[1].id for [2] in schematic.components if [3] == 'resistor']

Drag options to blanks, or click blank then click option'

Acomp

Bcomponent

Ccomponent.type

Dcomp.type

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing variable names in the loop and condition.

Checking the wrong attribute for type.

We iterate over component in schematic.components. To filter by type, we check component.type equals 'resistor'. The list collects component.id.
