Arduino实现WINDOWS+R快捷键失败求助：代码异常排查

看起来你遇到的核心问题是Windows+R组合键没有被系统正确识别——毕竟当记事本已经打开时，后续的文本输入都能正常工作，说明Keyboard库本身的功能是没问题的。

问题出在组合键的触发逻辑上：你现在是同时按下Win键和R键后立刻释放，但系统识别组合键需要一点时间来确认两个按键是同时按下的，太快释放会让系统误以为是两个单独的按键点击，而不是组合操作。

修正后的核心代码片段 #

把你触发Win+R的那段代码改成这样，给系统足够的识别时间：

// 触发Windows+R组合键
Keyboard.press(KEY_RIGHT_GUI);
delay(50); // 给系统时间识别Win键按下状态
Keyboard.press('r');
delay(100); // 保持组合键按下状态一段时间
Keyboard.releaseAll();
delay(1000);

额外排查点（如果上述修改仍未解决） #

• 确认你的Arduino设备被系统识别为HID键盘：可以在Windows设备管理器的“键盘”类别下查看是否有对应的Arduino设备。
• 尝试替换为左Win键：把KEY_RIGHT_GUI改成KEY_LEFT_GUI，有些系统或外接设备对左右Win键的响应可能存在差异。
• 关闭拦截Win键的软件：比如游戏手柄映射工具、键盘增强类软件，它们可能会占用Win键的输入信号。
