I find that my bedroom often is a different temperature than the bottom floor, where the heating system is based. Sometimes the room is hotter than downstairs, sometimes it is cooler. The thermostat system works by being set to heating or cooling to a specific temperature. If that temperature is read, the heating or cooling is then turned off. For instance, if the temperature is set to cooling to 66 degrees, the cooling is on until a temperature of 66 degrees is reached. If the temperature drops below what is set when on cooling, the thermostat doesn’t react. For this project, I want to be able to see if I should set the thermostat to a higher or lower temperature before I go to bed, so I can have a desired temperature of 65 degrees when I go to bed. I will accomplish this by using a thermistor, as well as an LCD display and a RGB LED. The procedure will be to develop a schematic where the thermistor senses the temperature in the room, the LCD display shows the temperature and the RGB LED shows a different color depending on what action I should take. For a temperature 64 degrees and lower, the light will show red and that will tell me to set the thermostat to heating and a higher temperature. For a temperature 64-66 degrees, the light will show green, and I will know that no action is required. For a temperature above 66 degrees, the light will show blue, and I will know to set the temperature to cooling at a lower temperature. For the power source I will use some rechargeable batteries that I have. The necessary coding will be through Arduino, and I will connect my power source and schematic to my Arduino Uno.
