Introduction: Arduino Thermostat Project

A way to simulate a thermostat using Arduino

Step 1: Materials

These are the materials you will need to make the thermostat

  • 1 LCD Screen
  • 2 Potentiometers
  • 1 Button
  • 1 LED (any color is fine)
  • 25 wires
  • Arduino Uno
  • Breadboard

Step 2: Instructions

First setup the LCD, normally you can look up the steps on how to put it together. Next, after the LCD is up and running, setup the temperature sensor so that it displays onto the LCD. Third step is that you need to set up the button so that when you push the button it changes the temperature from Fahrenheit to Celsius. Now that the temperature can change from Fahrenheit to Celcius, add a potentiameter, so that you can have a desired temperature, with that potentiameter you will be able to change the desired temp. Lastly you need to set up a LED light, colors may vary, and have it turn on if the actual temp. is higher than desired temp.

Step 3: Code

Step 4: Simulating an Air Conditioner

Once everything is up and working and you can see your LCD display, you should be able to, with the second potentiameter you should be able to move the dial and the desired temp. should be moving up or down. If the desired is lower than the actual temp. the LED should light up. If it does light up, and the LCD shows actual and desired temps. then it works, congrats.
