Embedded Systems Engineering has grown in recent years to become an integral part of our daily living as it finds striking applications in various spheres of our lives. These range from Manufacturing, Electronic Health, Telecommunications, Construction and Robotics to numerous other fields. Primarily, Embedded Systems are usually a combination of selected electrical and electronic components functioning together under the direct control of a programmed controller. They serve fundamentally as additional units incorporated within already existing infrastructures with the sole aim of providing dedicated services to the larger infrastructure. Many of the controllers used operate on uniquely designed processor cores, instruction sets, and architecture profiles. This paper seeks to elucidate the application of the ARM Cortext-M3 processor based NXP LPC 1768 Microcontroller unit in the design and development of a Temperature Monitoring and Logging System. The write-up starts off with an overview of the principal ARM processor core families, architecture profiles, instruction sets and subsequently, demonstrates its utilization in the design of a Temperature Monitoring and Logging System. The paper shows how the NXP LPC 1768 Microcontroller Unit successfully serves as the brain of the temperature logger device through its standardized interfacing with a TMP102 temperature sensor using the Inter- Integrated Circuit (I2C) protocol. The Microcontroller is programmed using Embedded C while other unique functionalities of the ARM Cortex-M3 core such as Interrupt Handling and System Tick Timer efficiency are also explored.

Considering the rapidly growing world population and increased enrolment in full course primary school education around the world, this paper elucidates key means of leveraging Information Technology for the effective and efficient management of the increasing pressure associated with schools' administrative functions and students' basic activities. Primarily narrowing down to the basic African education framework, this paper sheds more light on the methods which can be adopted for the development of such processes through improved Information Technology platforms. In doing this, the design and implementation of the Jasper School Management System (a school management solution developed by the author) will be used as a case study. Also, a brief highlight of the impact this Information Technology initiative will have on institutions where it is deployed. The Jasper School Management Software being referenced was built using Java Programming Language in conjunction with MySQL. It was produced to help improve management activities of schools especially in developing countries of the world, with 8 major school management modules incorporated into it. Also, the software is open-source i.e., open to adaptations, improvements and free to download.
