| Arduino101 | Interact with Arduino 101 devices and connected peripherals. Requires the BluetoothLE extension above. | MIT App Inventor | Arduino101.aix | Via GitHub |
| ImageProcessor | ImageProcessor can do a weighted combine of two images, return the greyscale of an image. Download this demo. | Justus Raju | ImageProcessor.aix | Source.zip |
| ScaleDetector | Adds as multitouch scale gesture detector to a Canvas. See Using App Inventor extensions to implement multitouch for an explanation of how this works. | Hal Abelson | ScaleDetector.aix | Source.zip |
| SoundAnalysis | Multimedia component that analyzes the pitch of a sound through the microphone and returns it. It can be used as an input to different situations, for instance to control some components with a specific sound whistle(pitch > 500Hz) or clap(pitch > 2000Hz). | Mouhamadou Oumar Sall | SoundAnalysis.aix | Source.zip |
| SoundPressureLevel | Measures the sound pressure level using the microphone and returns the data in decibels. Further documentation for users and developers can be found here. | RIT App Inventor | SoundPressureLevel.aix |
