// do something different depending on the character received. // The switch statement expects single number values for each case; // in this exmaple, though, you're using single quotes to tell // the controller to get the ASCII value for the character. For // example 'a' = 97, 'b...
手机搜索蓝牙,输入密码并连接。 之后选择Switch mode。 对按键进行设置。 点击APP 上的开关,就能够实现控制 LED 了。 实际结果 LED 打开: LED 关闭: 心得总结 昨天晚上鼓捣了很久,都没有出现正确的结果,后来才发现,控制 LED 开关的时候波特率设置成了 38400,应该设置成 9600。而 38400 这个波特率是进入 AT 模式...
Description:This is a simple ON/OFF switch for the LilyPad. When the switch is in the ON position it is closed and when it is in the OFF position it is open. Use it to trigger behavior in your programmed project, or to turn LEDs, buzzers, and motors on and off in simple circuits....

[File: toggle_switch_no_debounce.ino] The ProblemThe problem is that push button switches have an internal spring that does not settle immediately. So when you push it, it takes time to settle down and bounces up and down, producing lots of on-off transitions (even if you think you ...

* Built-in LED on pin 13 Unlike pinMode(INPUT), there is no pull-down resistor necessary. An internal 20K-ohm resistor is pulled to 5V. This configuration causes the input to read HIGH when the switch is open, and LOW when it is closed. ...
