ABOUT BTduino - Arduino - Bluetooth
BTduino 是利用手機藍芽裝置(Bluetooth)連接 Arduino 的應用程式。此程式現提供數字按鍵模式及遊戲控制器模。往後亦會加入PWM，各種感應器及按鍵配對等功能。使用者需連接藍芽接收裝置如HC06至Arduino。藍芽HC06連接Arduino的設置如下： 1. 藍芽VCC接Arduino 5v或3.3v(視乎所購買的裝置而定) 2. 藍芽GND接Arduino GND 3. 藍芽RXD接Arduino TX(Pin10) 4. 藍芽TXD接Arduino RX(Pin11) // Arduino RX(Pin 11) connect to Bluethooth TX, Arduino TX(Pin 10) connect to Bluethooth RX
