This is a common mistake for beginners who just got started to learn programming.
It is very easy to solve. You just need to declare variable by one of two following ways:
Declare a variable as a global variable. int myVal; void setup () < // put your setup code here, to run once: myVal = 5; >void loop () < // put your main code here, to run repeatedly: > Declare a variable as a local variable. void setup () < // put your setup code here, to run once: int myVal = 5; >void loop () < // put your main code here, to run repeatedly: >Please note: These are Amazon affiliate links.
