App Inventor
MIT App Inventor allows anyone, including children, to build mobile apps with ease.
There are 2 ways to access DUELink modules from App Inventor, either USB or Bluetooth.
Examples are provided to get you started but this is an experimental support. Consider one of the fully supported options, such as Python.
USB
This only works with Android as iOS does not support the standard USB CDC Class. As for the modules, you can either use one of the modules with built in USB, such as the ultra-low-cost CincoBit or add USB Hook.
Wireless
Wireless is a bit easier as there is no physical connection to the phone or tablet. These devices can pair with Wireless Hook, which in turn brings the chain of DaisyLink devices to the Wireless connection via WiFi or Bluetooth.
Demo
This demo includes both USB and Bluetooth. Log in to App Inventor and then load this file
