Introduction: Just Make It!! BT Smart Fan :)

I will introduce a BT Smart Fan :)
You can make bluetooth smart fan if you follow this contents.
It is very easy and simple way.
Let's start!

Step 1: Prepare Meterials

We need a several meterials

  1. WIZwiki-W7500 board
  2. Arduino Motor Shield
  3. Easy Module Shield(not absolutely necessary)
  4. JMOD-BT-1(HC-05) bluetooth module
  5. Servo motor(SG-90)
  6. DC motor(5V DC motor)
  7. Rubber eraser (just support DC motor any object)
  8. Some scatch tapes
  9. DC jack(connect Motor Shield)
  10. Some hexagon spacer nut/screw
  11. Some cables
  12. USB mini B type cable
  13. 5V DC Power Supply

They are all... for this project~!

Step 2: Hardware Connection:Servo+WIZwiki-W7500

connect SG-90 Servo Motor and hex nut.

Step 3: Hardware Connection:Servo+WIZwiki-W7500

Hex nut/screw connect each corner portion.

Step 4: Hardware Connection:Servo+WIZwiki-W7500

the finished connect servo and WIZwiki-W7500.

Step 5: Hardware Connection:DC Motor + Rubber Eraser

DC motor and Rubber Eraser wrap with tape.

Step 6: Hardware Connection:Arduino Motor Shield+DC Motor+DC Jack

DC motor and DC jack connect Arduino Motor Shield~

Please refer to the picture.

Step 7: Hardware Connection:Arduino Motor Shield+WIZwiki-W7500

Motor Shield mounted on the WIZwiki-W7500.

Step 8: Hardware Connection:Servo + DC Motor

DC Motor maounted on the Servo.

Step 9: Hardware Connection:Arduino Motor Shield + Easy Shield

Easy Shield maounted on the Arduino Motor Shield.

Step 10: Hardware Connection:Easy Shield + Servo

Servo cable connect to easy shield (GND,VCC,SDA(change function to PWM using software))

Step 11: Hardware Connection:Easy Shield + JMOD-BT-1

JMOD cable connect to easy shield pin (GND,VCC,TX,RX).

Step 12: Hardware Connection:Connect Power Supply

DC jack and USB cable connect.

Step 13: Prepare Development Environment

I prepared mbed develpment environment by the following site.

You not installed Tool, Just use Internet.

To get start with go on side and create free account.

If you are ready open compiler and create first project.

Step 14: Reference Software : Mbed

Source code is

You import this program and compile using mbed internet compiler.

You can get bin file.

Step 15: Reference Software : Smart Phone

download smartphone application.

blueterm is bluetooth serial terminal.

Step 16: How to Run : Test Result

You can see the test result by the video.
Thank you for your attention.

Step 17:
