The objective of this paper is show the development of an Eletronic Control Unit (ECU) for Baja-SAE vehicles from its requirements to final implementation. An ECU for Baja-SAE vehicles is made of electric and electronic circuits (appropriated to the hostile situations of an off-road competition) able to make important measurements for the running or stand-by vehicle performance. For this development, some concepts were studied: embedded electronics concepts (mainly microcontrollers and data acquisition circuits) and sensoring. Both the studies were made considering the off-road environment. After these initial studies, the elaboration of the basics hardware and software (under simulations) has begun, and this elaboration objectives maximum performance and low implementation cost. After the theorical studies, basic definition of the hardware and software’s architectures and simulations, the printed circuit boards (PCB) were made, as exhaustive tests in these boards for debugging and verify if the boards work well. Once the system was tested in the university, it ran into a regional Southeast competition in 2010, that definitely proved the efficiency of the whole system

This work research and analyses the formulations and concepts of heat and temperature presented in Physics textbooks. These issues are deemed important because students often have difficulties differentiating and understanding such concepts, which compromises their education. The goal is to show that well-established relationships between Physical quantities such as energy, pressure, heat and temperature, even in different theories of Classical and Quantum Physics are not enough to define either temperature or heat. It also presents simple experiments that complement the teaching and learning of these concepts
