As your room’s temperature changes, the Arduino will also adjust your AC’s set temperature to maintain your temperature in just the way you want it to be. So if you are a absolute newbie to OLED, DHT11 or TSOP then kindly fall back to these tutorials below where you can learn the basics and how to get started with these. We commonly use temperature control systems in Air Conditioners, Refrigerators, geysers, etc. For example, when you decrease the temperature using the down button to make it 24°C (degree Celsius) you will get a signal with a set of data, but when you press it again to set 25°C you will not get the same data since the temperature is now 25 and not 24. This project uses a PIC microcontroller to automatically control the temperature of an area.  */   AC_Temp = 25;  token, Good evening. #define OLED_DC    5 The concept of this paper is to create an automatic temperature control system to control the temperature of a system.
