本文利用PS2手柄和Arduino开发板制作了一个简易的遥控小车,利用蓝牙进行通信,可以实现前后左右的移动。(原理掌握之后可以自己拓展相关功能) 一、零件 1.Arduino UNO开发板: ArduinoUNO是ArduinoUSB接口系列的最新版本,作为Arduino平台的参考标准模板。UNO的处理器核心是ATmega328,同时具有14路数字输入/输出口(其中6路可作...
The transistor-controlled relay mentioned above enables you to switch very large amounts of current on or off. This enables you to switch large devices such as your washer/dryer, heater, air conditioner, car starter, among other things on or off with your Arduino. ...
