Introduction: Arduino Air Conditioner Simulator
*Note: The reason that an LED is being used instead of a fan is that every time the motor ran the LCD would show Gibberish*
Step 1: Materials
- 1 x Arduino Uno
- 1 x Breadboard
- 1 x LCD
- 3 x 330 ohm resistor
- 2 x Potentiometers
- 1 x button
- 1 x temperature sensor
- 1 x led
- 25 x wires
Step 2: Create the Circuit
To create the circuit follow the schematics carefully. It is extremely easy to get confused. If nothing shows up on the LCD or only blocks are showing up mess with the potentiometer that is connected to the LCD. If gibberish is being displayed on the LCD make sure the wires are correctly connected.
Step 3: Program
Download the program to the Arduino, then the LCD should turn on and display the room temperature and the desired temperature.
Step 4: Simulate an Air Conditioner
To change the desired temperature change the potentiometer that is connected to the pin A1. The LED simulates the use of a fan and should only turn on when the desired temp is cooler than the actual temp. The button will allow the user to change between Celsius and Fahrenheit.
