Create a fan that can be controlled whenever it gets hot or cold enough. It’s great for when you have to work on a hot day and don’t want to get too overwhelmed by the temperature.

Supplies

Temperature sensor
18 Wires
LCD sensor
Arduino UNO
Breadboard
32k ohm resistor

5V fan
6V battery case

Step 1: Connect Wires to Arduino

Connect all of the components to the Arduino using the wiring diagram showed.

Step 2: Upload Code to Arduino

You can easily adjust the speed of the fan by changing the code in the sensor area. You can raise or lower the temperature that the fan activates at based on your environment.

Step 3: Modifications

The project works right now and is ready for use, but if you would like to create a case for the circuit so that it doesn’t look as bare, the dimensions are
6.875x5.185x 6
