Improvement of IOIOAI service for external sensors communication between app inventor and ioio

Internet of Things (IoT) is currently leading the next world revolution. We witness more and more wearable devices and soon, all everyday objects will have a tiny computer. The ultimate objective of IoT is to leverage the technology abstraction as much as possible. Several fields are benefitting from the IoT revolution, among them we cite electronics, Computer Science (CS) and education. There is a recent trend that focuses on developing HardWare (HW) or SoftWare (SW) solutions that facilitate the process of learning electronics and CS and can be integrated in the educational field. However, the existing solution focus on one of these sides and a combination of both HW & SW is quite rare. In this context, we present our developed solution that brings more simplification to the programming task for mobiles. It consists of an android service that links the features of the IOIO electrical board and the App Inventor android programming platform. This combination allows to user to develop Android apps that can control the IOIO board via Bluetooth and the board will interact with other electrical components connected to it. In this paper, we introduce the general overview of the system and present an improved version of the developed service that integrates support for additional commands to make App Inventor Apps capable of reading sensors connected to the IOIO board.
