Arduino 循环 do ... while循环类似于while循环。在while循环中,循环连续条件在循环开始时测试,然后再执行循环体。do ... while语句在执行循环体之后测试循环连续条件。因此,循环体将被执行至少一次。 当do ... while终止时,将使用while子句后的语句继续执行。如果在正文中只有一条语句,则没有必要在do ... whi...
我使用do-while循环创建了它,问题是菜单选择变量是int,所以当我(或用户)在从菜单中选择时意外地输入非int输入时,主循环末尾的}while(condition)无法捕捉到它,程序会无限重复。相反,如果在菜单选择处输入无效的int,程序会捕获它,显示“无效输入”消息,然后重复主菜单。很难用书面的方式来解释我的意思,所以这里是用星...
For i = 1 To 5 j = 1 Do While j <= i ' 执行一些操作 j = j + 1 Loop Next i 在这个示例中,外部循环For i = 1 To 5会执行5次,内部循环Do While j <= i会根据外部循环的当前迭代次数执行不同次数的操作。 嵌套do while循环的for循环在实际开发中有多种应用场景,例如: 数据处理和分析:可...
while [condition] do first command; second command; . . . nth command; done A while loop’s parameters can be any boolean expression. When the conditional never evaluates to false, the loop becomes infinite. Hit CTRL + C to stop the infinite loop. Let’s look at an example: #!/bin...
As for the Arduino side, I think you have a mis-understanding of how the digitalWrite function works. Once you set a pin on or off, it remains in that state until you toggle it to the other state. This means you do not need to constantly tell it to stay on in a while ...
(SOFTAP_IF, &newMACAddress[0]); // For Station Mode wifi_set_macaddr(STATION_IF, &newMACAddress[0]); //set mac 1 } else wifi_set_macaddr(STATION_IF, &newMACAddress2[0]); //set mac 2 } WiFi.begin(ssid, password); Serial.println(""); // Wait for co...
Take a look at the entire code below and you will see how to turn both LEDs on at the same time in the do…while loop. unsigned long counter; void setup() { pinMode(D5, OUTPUT); } void loop() { // Turn LED A on B off ...
void loop() { while (Serial.available()>0){ serialByte=Serial.read(); if (serialByte=='S'){ while(1){ fanalog0=eHealth.getECG(); // Use the timer0 => 1 tick every 4 us time=(timer0_overflow_count << 8) + TCNT0; // Microseconds conversion....
While on USB 3.0 ports, it tried to use the SSTX/SSRX pair and it doesn’t work. I hope this helps others that have the same problem. Just a word of caution: the colors of your cables might be different from the one that I have, the PCB layout that you receive may also be ...
Right: fake Arduino. Left: Unofficial clone. But if the hardware is the same, why would you buy a "fake" Arduino? While an official board can retail at over $20, you'll find clones with the exact same functionality for less than $5. You can even buy all the components individually ...
