This Paper describes the new Paradigm in the Teaching and Learning of Embedded and Microcontroller programming and Application Development. The Authors use the STEMSEL Microchip Programming methodology to teach the Application Development for Pervasive Computing Environments. In the recent years the development of Applications in Ubiquitous environments with the use Internet of Things has triggered a massive research challenges and intensive programming needs. This paper explains the use of a new Integrated Development Environment using simple Graphical Drag and Drop based tool to program such applications. This is applied to develop applications using Bluetooth , WIFI etc for various pervasive computing needs. This Integrated Development Environment is very useful to Teach & Learn such technologies in a simple and quick way. In this paper , it is shown that the use of STEMSEL Microchip technology in Teaching, Learning, Development of Pervasive Applications will reduce Learning Time & Time to Market the Applications.
