Entertainment centers often trap heat given off by electronics; this can cause them to overheat which reduces their lifespan. This project can be used to regulate the temperature of an entertainment center by increasing air flow. It does this by allowing users to control two different fans and a servo. The fans will automatically turn on if a certain temperature is reached and the servo will turn 90 degrees. If a user knows they are about to generate a lot of heat they can switch to manual fan control by flipping a slide switch. Once this switch is moved, the fans will turn on one at a time with each click of a button switch and the servo will turn on the second click. Once the switch has been clicked three times, the fans will turn back off, and the servo will return to its starting position. This would help regulate the temperature of any device in an entertainment center without always running your fans which would reduce the life of your fans and waste electricity.

Step 1: Materials

1) Temperature sensor [TMP36] (250 mV output at 25°C)

2) Slide switch

3) Two 240Ω resistors

4) 100 uF electrolytic capacitor

5) Tactile button switch

6) Breadboard(I use an Explorer Board)

7) Two PWM controlled fans(I use two different sizes in my demo)

8) Small servo motor

9) ChipKIT WF32

Everything but the fans and the ChipKIT is included in the LabVIEW Interaction Parts Kit
