that between the parenthesis the number of the input is compared with the different cases.
In particular, a switch statement compares the value of a variable to the values specified in the case statements. You connect one of those either to Ground (LOW) or 5V (HIGH) and connect the other one to an Arduino Digital pin. For example 'a' = 97, 'b' = 98, // and so forth: switch (inByte) { case 'a': digitalWrite (2, HIGH); break… This is an example of ‘FLOATING’ When the switch is pressed it makes the connection between those two pins and connects the Arduino Digital pin to either Ground or 5V which we can detect in code and do the appropriate action. Similar to the if statements, switch...case controls the flow of programs by allowing the programmers to specify different codes that should be executed in various conditions.

If a case is equal to colorChoice the lines, in that case, are executed.If the input of the user is not valid, we using the default and print statement to let the user know that their input is not valid.Remarkable! When the word default is used within a switch statement it will be executed if no value of the cases matches the expression value.Besides default, there is also the word break. // The switch statement expects single number values for each case; in this // example, though, you're using single quotes to tell the controller to get // the ASCII value for the character. First of all, we need to ask the user for input.The second part is to wait for input from the Serial monitor. switch (var) { case 1: //do something when var equals 1 break; case 2: //do something when var equals 2 break; default: // if nothing else matches, do the default // default is optional break… The expressions could be an integer or a character. The photoresistor is connected to analog in pin 0 using a voltage divider circuit. Si vous continuez à utiliser ce dernier, nous considérerons que vous acceptez l'utilisation des cookies.
switch {case: break; default:}. Remember, we can only receive numbers and characters through this method. Page d'accueil de la référence Arduino en français. The expressions could be an integer or a character. Le signal possède 3 feux : vert, jaune et rouge.

In the above example, you can see the general code for a switch statement. Exemple 2 : #include
