Project Description

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!

Prepare materials:

  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

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

fan-8

Easy Shield mounted on the Arduino Motor Shield.

Step 10: Hardware connection:Easy Shield + Servo

fan-9

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

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

fan-10

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

Step 12: Hardware connection:Connect power supply

fan-11

DC jack and USB cable connection.

Step 13: Prepare development environment

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

You not installed Tool, Just use the Internet.

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

If you are ready to open compiler and create the first project.

Step 14: Reference Software: mbed

The 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.

Step 15: Reference Software: Smartphone

fan-12

download smartphone application.

blueterm is Bluetooth serial terminal.

Step 16: How to run: Test result
