WIZnet / SmartFan_WIZwiki-W7500

BTSmartFan Servo/DC motor controlled using Bluetooth

Dependencies:   Servo mbed-dev

Fork of BTSmartFan_WIZwiki-W7500 by justin kim

Prerequisite

This example is to control a servo motor and DC motor using bluetooth.

To implement this function, you need a Platform board, Easy Module Shield V1, Bluetooth module, DC jack, 5V DC Power Supply.

Below are what we used.

  • WIZwiki-W7500 from WIZnet (Platform board)
  • Arduino Motor Shield
  • Easy Module Shield(Not mandatory)
  • HC-05 bluetooth module
  • Servo motor(DM-S0300D)
  • DC motor(5V)
  • DC jack
  • 5V DC Power Supply

Software

BlueTerm (Application)

download a BlueTerm App to send a command message to bluetooth module with smart phone.

Pins setting

main.cpp

Serial pc(USBTX, USBRX);
Serial bt(PA_14, PA_13);
Servo myservo(D14);
PwmOut Motor(D3);
DigitalOut direction(D12);

Baud rate

main.cpp

    pc.baud(115200);
    //bt.baud(115200);
    bt.baud(9600);
