Earlier updates

Scope, sensors & audio

• Added advanced scope controls. This allows precise scale and offset adjustments.

  

• You can now measure signals within a selected range and perform precise measurements including range calculations.

  

• New component: Microphone. This component will use device microphone to inject audio into circuit as signal like a real mic.

  

• New component: Audio File Input. This component will read an audio file and inject audio into circuit as signal.

  

• New extension: Device Sensors. This extension gives access to 11 new components, which would give access to mic, flashlight, volume switch, gyroscope, etc

  

• New component: SR Latch. This is a basic digital circuit that stores one bit of data and has two inputs Set and Reset.

Workspace & editing

• Added backup and restore feature to save and recover all your projects.

  

• The examples screen has been redesigned for easier access, and new examples have been added.

  

• The multimeter has been redesigned. You can now hold the display and lock the selection mode.

  

• You can connect a node to any section of the wire by clicking it in connect mode. The wire needs to be snapped to the grid.
• Improved movement of component when they are snapped to grid
• New component: IONode. This component will mark a node as CustomIC pin. Digital IO pins can be set as IONode.
• The guide button in component bottom bar will give you a short description and usage of that component

  

• Grid snapping for wires is now available to enable.
• Now if a component is moved to a wire it will autoconnect. If a node overlaps with a wire without connecting, its color will change to orange

Major redesign

• The app has been redesigned with a strong focus on user experience (UX).

  

• Redesigned scope info bar to show better info.

  

• Now you can create IC with user defined internal circuit. Use the package button to package the current circuit.
