If 语句 它采用括号中的表达式,后面跟随语句或语句块。如果表达式为真,则执行语句或语句块,否则跳过这些语句。 If … else 语句 一个if语句后面可以跟随一个可选的else语句,当表达式为false时执行。 If … else if … else 语句 if语句后面可以跟随一个可选的else if ... else语句,其对于测试各种条件非常有...
void loop() { delay(100); if ( S1() ) digitalWrite(LED1, 1); else digitalWrite(LED1, 0); } Test 1 Note: true = 1; false = 0. Or should I say any value except 0 is TRUE. Note the code above. An "if" statement has the general form of: if (condition) light_led1; els...
Codes in the body of theifstatement andif-elsestatement don’t run. Below is an example showing how to use theif-else-ifstatement: intMarks=95;char Grade;voidsetup(){Serial.begin(9600);if(Marks<=33){Grade='E';}elseif(Marks<=40){Grade='D';}elseif(Marks<=60){Grade='...

if(ITerm > outMax) ITerm= outMax;elseif(ITerm < outMin) ITerm= outMin;// 求出两个被控量之间偏差,也就是在计算周期(这里不用采用周期是因为计算周期可能会超过采样周期)被控量的变化。// 其实就是微分项的 因子,但是看起来和标准表达式也不一样啊!!!// 。。。一两句也说不清楚,总的来说是为了...

For example: int value = 0; int sign = 1; void loop() { if( Serial.available()) { char ch = Serial.read(); if(ch >= '0' && ch <= '9') // is this an ascii digit between 0 and 9? value = (value * 10) + (ch - '0'); // yes, accumulate the value else if( ...
