It will operate an H-Bridge with speed control for both directions. Or will operate two single motors with independent speed control for each motor. It will also have a master ON-OFF power control. It will go into more uses for "if-else" statement. void loop() { delay(100); if (...
Arduino Programming: “if” statements Mechanical and Materials Engineering Portland State University http://me120.mme.pdx.edu/ Overview Motivation: The need for conditional execution “if” statement concepts Logical expressions Examples On-line reference: https://www.arduino.cc/reference/en/language/s...
它在括号和语句或语句块中使用表达式。 如果表达式为true,则执行语句或语句块,否则将跳过这些语句。 不同形式的if语句 Form 1 if (expression) statement; 如果您有一个语句,则可以使用不带大括号{}的if语句。 Form 2 if (expression) { Block of statements; } if语句 - 执行顺序 例子(Example) /* Global...

Arduino switch case : Find out how to write compact code with multiple conditions and how to reduce long lines of 'if-else' into short code. Get it right First Time.
every statement ends with a semicolon ; void setup(){ }is the function that runs once, when the Arduino starts up void loop(){ }is the function that repeats forever, after the setup has run pinMode(pin,OUTPUT);orpinMode(pin,1);sets the given pin as an output ...

So for example if we click the Forward button, the blocks in the “if” statement will be executed. That means we will send the number 2 to the Arduino and that will execute the move forward set of functions. At the same time we can notice that we change the image of the button to...
