In the previous tutorial, we learned to blink LED by using the delay method. That method blocks Arduino from doing other tasks. In this tutorial, we are going to learn another method to blink LED without blocking other tasks. The detail instruction, code

After rewriting the code you usually have to define variables used in the original "if else" block of code as static, as shown, so that all functions in the file can access the variables. See the 'command' variable for an example.Note...

When a true test is found its associated block of code is run and the program then skips to the line following the entire if/else construction. If no test proves to be true the default else block is executed if one is present and sets the default behavior. Note that an else if block...
True or false (click to find out) False: You can use a do while loop to execute a block always once which is not possible with a for loop. This is only true in trivial form - you can write code to detect the initialiser variable and break out of the loop but it is far more ...
