Abstract This temperature control fan can be controlled using a microcontroller when it detects a certain temperature that has been set. The purpose of this project is to prevent the waste of voltage usage when it is not hot enough for fan to be needed. The temperature control fan has three different speeds. Each speed will change according to a certain level of temperature that is set. This project is a combination of electric supply, fan, temperature senso...
