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!

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~!

connect SG-90 Servo Motor and hex nut.

Hex nut/screw connect each corner portion.

the finished connect servo and WIZwiki-W7500.

DC motor and Rubber Eraser wrap with tape.

DC motor and DC jack connect Arduino Motor Shield~

Please refer to the picture.

Motor Shield mounted on the WIZwiki-W7500.

DC Motor maounted on the Servo.

Easy Shield maounted on the Arduino Motor Shield.

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

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

DC jack and USB cable connect.

I prepared mbed develpment environment by the following site.
https://developer.mbed.org/

You not installed Tool, Just use Internet.

To get start with mbed.org go on side https://developer.mbed.org/ and create free account.

If you are ready open compiler and create first project.

Source code is https://developer.mbed.org/users/justinkim/code/BTSmartFan_WIZwiki-W7500/

You import this program and compile using mbed internet compiler.

You can get bin file.

download smartphone application.

blueterm is bluetooth serial terminal.

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