The role of the temperature controller is to measure the value on the temperature, compare it to the set point and calculate the amount of time the hot water solenoid valve should remain switched on to maintain a conandstant temperature. How accurately we need to control the temperature will also determine the type of temperature controller we have to use. The manual is organized into four chapters, three of which explain how the code and hardware can be integrated so that a relay can be turned on and off to control the temperature of a small water filled container using a typical ATmega8 Microcontroller. The last chapter explains how, by applying two SSR’s (solid state relay), the temperature of the same container with a PID control can be managed using an Arduino ATmega2560 development board.
The main control program solutions are prepared in C language using CodevisionAVR and Arduino software. In addition, the schematic of all the hardware used in these projects are available in the text. You will find details on the creation of code for an ATmega8 Microcontroller and Arduino development board that controls a temperature process in the text. This book has been prepared for those who are already familiar with the basic instructions related to any brand of Microcontroller and may have already developed some Microcontroller-based programs for different purposes. Developing this will give you an idea of either how to implement a relatively complex end year college project or give you enough hands on experience to apply for an entry level job on applications of Microcontrollers with full confidence.
