智能小車做爲現代的新發明,是之後的發展方向,他能夠按照預先設定的模式在一個環境裏自動的運做,不須要人爲的管理,可應用於科學勘探等等的用途。智能小車可以實時顯示時間、速度、里程,具備自動尋跡、尋光、避障功能,可程控行駛速度、準肯定位停車,遠程傳輸圖像等功能。下面帶你們作一個智能藍牙小車,用手機APP來控制小車前進、後退、向左、向右、中止,本次藍牙小車的設計在於探索藍牙智能小車的設計理念及設計方法,學習一下PWM控制電機差速來控制小車的方向,下面就動手搞起來吧!!!!!html

3.藍牙模塊設計
藍牙( Bluetooth):是一種無線技術標準,可實現固定設備、移動設備和樓宇我的域網之間的短距離數據交換(使用2.4-2.485GHz的ISM波段的UHF無線電波)。
咱們在此使用的藍牙模塊(HC-06)已經在內部實現了藍牙協議,不用咱們再去本身開發調試協議。這類模塊通常都是藉助於串口協議通訊,所以咱們只需藉助串口將咱們須要發送的數據發送給藍牙模塊,藍牙模塊會自動將數據經過藍牙協議發送給配對好的藍牙設備。調試
4.單片機-TPYBoard v102code
TPYBoard v102 是遵循MIT協議,由TurnipSmart公司製做的一款MicroPython開發板,它基於STM32F405單片機,經過USB接口進行數據傳輸。該開發板內置4個LED燈、一個加速度傳感器,可在3V-10V之間的電壓正常工做。讓你會Python就能作極客, 用Python控制硬件,支持Python語言的開發板。比樹莓派更小巧,更簡單,更便宜,比Arduino更強大,更加容易編程。視頻
小車擴展板
以TPYBoard v102開發板爲主控板,小車擴展板具備四路PWM調速電機、8個可控LED、1個蜂鳴器、5路舵機接口、1個藍牙接口、1個PS2無線接口、引出TPYBoard v102開發板所有針腳,可裝載循跡模塊、超聲波模塊、機械手臂、紅外接收頭,兼容入門級電機和專業級電機,兩節18650單獨供電。htm
源代碼
咱們只須要把TPYBoard v102 插小車擴展板上,把藍牙模塊插上,把程序寫入就行,下面是main.py源程序
