![]() ![]() ![]() ![]() They are very simple and they do work well but, the problem arises while calibrating the threshold level using preset resistor or potentiometer. There are tons of non-microcontroller based automatic temperature controller projects available around the internet, such as using comparator and transistors. In this project the user just need to input the threshold temperature in the program, the microcontroller will take care of rest of the function. The beauty of microcontrollers is that, we get very precise control over the peripherals which are connected to it. ![]()
