char charValue[] = "1234";: This line initializes a character arraycharValuewith the value"1234". int intValue = atoi(charValue);: Here, we use theatoi()function to convert the character arraycharValueto an integerintValue. Serial.println(intValue);: This line prints the converted integer ...
On the first line, there's a new expression 'int delayTime = 200;' This is the so-called declaration of the variable 'delayTime'. A variable is just a piece of memory, where you can store pretty much anything you like. A variable has adata type, a name, and a value: in this ca...
