Can you do 2 void loops in Arduino?
Each function runs one at a time. But, since the delay has been removed from the light1/2 functions, they will end quickly during the ‘waiting’ period instead of pausing execution. This will allow the motor(s) to run and lights to blink all at the same time. No you cannot.
What is the function of the void setup?
Void setup is technically a function that you create at the top of each program. Inside the curly brackets is the code that you want to run one time as soon as the program starts running. You set things like pinMode in this section. The loop is another function that Arduino uses as a part of its structure.
What is the function of digitalWrite?
The digitalWrite() function is used to write a HIGH or a LOW value to a digital pin. If the pin has been configured as an OUTPUT with pinMode(), its voltage will be set to the corresponding value: 5V (or 3.3V on 3.3V boards) for HIGH, 0V (ground) for LOW.
What is difference between loop and function?
Answer: Just as a loop is an embodiment of a piece of code we wish to have repeated, a function is an embodiment of a piece of code that we can run anytime just by calling it into action. A given loop construct, for instance could only be run once in its present location in the source code.
Is it possible to make multiple void loops?
No you cannot. Not only is it no proper C/C++ to have multiple identical functions, i.e. it will not compile (as jfpoilpret’s comment suggests).
What are void setup and void loop functions in Arduino?
When you open a new program in the Arduino IDE, you immediately get empty void setup and void loop functions written for you. What are those void setup and void loop functions in Arduino?
Is it possible to have multiple loop functions?
As the others have stated, no you can’t have multiple loop functions. What you need to do is modify your approach so that each thing you are trying to do can be done sequentially without blocking (ie: remove the delay function usage). Expanding on some suggestions by JRobert, Here is how I would make these functions “run at the same time”:
When to use a void in a function?
Even without the return statement, control will return to the caller automatically at the end of the function. A good utilization of a void function would be to print a header/footer to a screen or file.
