If声明条件:使用一个‘if 声明’,通过改变输入条件来改变输出条件 Switch Case:怎样在非连续的数值里选择。 Switch Case 2:第二个switch-case的例子,展示怎样根据在串口收到的字符来采取不同的行为 While 声明条件:当一个按键被读取,怎样用一个while循环来校准一个传感器。
// 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...

Here's the example used in the original code above.switch(ch) { case 'a' : command = 10; break; case 'r' : command = 20; break; case 'z' : command = 30; break; default : command = 0; } If the character ch is not 'a', or 'r', or 'z' then the variable command is ...

考勤系统是用于标记办公室和学校存在的常用系统。从在考勤登记册中手动标记考勤到使用高科技应用程序和生物识别系统,这些系统都得到了显着改进。在我们以前的项目中,我们已经涵盖了使用RFID和AVR微控制器,8051和树莓派的其他电子考勤系统项目。在这个项目中,我们使用指纹模块和Arduino来获取和保存考勤数据和记录。通过使用...
(This could also be a motor control for example.) In each case pressing S1 or S2 returns a 1 or 0; the "if" command does the rest. Another note is the () must be used properly and in sets of 2. void loop() { if ( S1() ) { byte temp = digitalRead(LED1); temp = !
