This Receiver will be interfaced with Arduino to signal for each button and then an IR Led will be used with Arduino to mimic the signal when ever required. With the help of a microcontroller, the system responds by turning ON any of the two (2) loads (Fan or a heater) automatically depending on the temperature difference.   AC_Temp = 24;   Not used: C:\Users\mshaf\Documents\Arduino\libraries\Arduino-IRremote-master int Measured_Humi; For each different button on the remote a unique signal will be blasted which after read by the receiver is used to perform a particular pre-defined task. #define OLED_RESET 7 In file included from C:\Users\18766\Documents\Arduino\__\__.ino:28:0: C:\Users\18766\Documents\Arduino\libraries\Adafruit_SSD1306-master/Adafruit_SSD1306.h:91:0: note: this is the location of the previous definition, #define SSD1306_LCDHEIGHT 32.
