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
- WIZwiki-W7500 board
- Arduino Motor Shield
- Easy Module Shield(not absolutely necessary)
- JMOD-BT-1(HC-05) bluetooth module
- Servo motor(SG-90)
- DC motor(5V DC motor)
- Rubber eraser (just support DC motor any object)
- Some scatch tapes
- DC jack(connect Motor Shield)
- Some hexagon spacer nut/screw
- Some cables
- USB mini B type cable
- 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.
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.
Step 14: Reference Software : Mbed
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 : 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.
