在PonyProg中对ATmega168勺熔丝位设置为下图所示:熔丝位设置好之后,选择“Command菜单中的“WriteAll”命令,将bootloader下载到Arduino中。下载过程中Arduino上的发光二极管L会不断闪烁。下载完成之后,我们可以通过Arduino集成开发环境下载一个Arduino工程,来验证新下载的bootloader是否能够正常工作。DIYArduino:HelloWorldArduino...

That takes the LED_BUILTIN pin back to 0 volts, and turns the LED off. In between the on and the off, you want enough time for a person to see the change, so thedelay()commands tell the board to do nothing for 1000 milliseconds, or one second. When you use thedelay()command, n...
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...
