Arduino while用法及代码示例【控制结构】 说明 while 循环将连续无限循环,直到括号内的表达式 () 变为 false。有些东西必须改变被测变量,否则while循环将永远不会退出。这可能在您的代码中,例如增量变量,或外部条件,例如测试传感器。 用法 while (condition) { // statement(s) } 参数 condition :一个布尔表达式...
示例代码 花括号的主要用途在下面的示例中列出。 职能 voidmyfunction(datatype argument){// any statement(s)} 循环 while(booleanexpression) {// any statement(s)}do{// any statement(s)}while(booleanexpression);for(initialisation; termination condition; incrementing expr) {// any statement(s)} 条...
Arduino While loop example 9 to 0 To output a sequence from 9 down to 0 you must initiailise the loop value to the 1st output value you want before reaching the while statement; in this case variable 'i' is initialised to 9.

Finally, close up your brackets from theifstatement, while statement, and main loop : 最后,为判断语句、循环语句和主循环敲上封闭的大括号。 Once you have programmed the board, open your Arduino Software (IDE) serial monitor. Make sure you have chosen to send a newline character when sending ...
Practicalexamples and analysisof common Arduino functions. On this Arduino reference page you can find links to common Arduino functions so you can find out how they work, and how you should use them. Some functions are obvious while others have obscure and subtle problems of which you should ...

Inside of your if-statement, you can also use logical operators (Boolean operators), to check multiple conditions: && (and), || (or) Some examples: 5 > 3 → true 5 < 3 → false 3 > 3 → false 3 >= 3 → true 5 != 3 → true 3 == 3 → true to check if a value x is...
