Switch case inside switch case arduino serial#
It uses the serial monitor to show what is going on in the code. In particular, a switch statement compares the value of a variable to the values specified in case statements. switch. The switch case that in in the main loop function will move the linear actuator (I have actually built a small mock-up of the mechanical functions including limit switches, accelerometer, relays and actuators), but ignores the limit switches or any control statements put in to read the accelerometer. switch.case Control Structure Description Like ifstatements, switch casecontrols the flow of programs by allowing programmers to specify different code that should be executed in various conditions. (I will add real cases over time as they appear as questions in the forum) Thanks for the replies, Yes it does compile. One IO-pin LOW for 2 minutes in parallel blink LED / check for. So I want to add some typical cases here to make it easier to find this threadĬreate 5 pulses ON/OFF then go on (IO-pin LOW / HIGH) In the real world billions of variations of this functionality can be found Or even more complex if A then go on way 1 if B continue with way 2 Two, three or more things "at the same time".Īnd/or several steps must be executed in a well defined sequence As It's wrote below, the sketch is working perfectly, especially if considering the situation in which every function returns one single value. In particular I've Imagined a sketch with a 'switch case loop' for the function selection. Sooner or later almost every coder comes across that she/he needs a functionality that does Hi, I would like to create a sketch that execute some different function (sensor measurements) depending on which key is pressed by user. Can you please take a loot at function being defined correctly. If you don't like it or don't understand it you can not define a function inside another function. To offer a wider range of how it can be explained. There are a lot of different approachs to explain something.
The break keyword is used at the end of each case. When the statements in a case matches the value of a variable, the code associated with that case executes. A switch statement compares a particular value of a variable with statements in other cases. You just open the serial monitor to watch the behaviour of the code.įrom time to time I enjoy writing demo-codes that want to explain programming-functionalities. The switch case controls the flow of the program by executing the code in various cases.
