as3Glue gives Flash, Flex and AIR applications physical interaction capabilities, enabling  communication between the apps and Arduino boards.

It can together with one or several Arduino boards be used to monitor sensors (such as rotary encoders and motion detectors), control actuators (such as LEDs and motors) and interface other electronics (such as RFID readers) from Flash, Flex and AIR applications.
