Hi, I have a problem with my Arduino project. My Sketch has multiple files with multiple functions and of course a bunch of vars, many of them are global. For the Arduino IDE it is not a big deal, I can use them in every file without the need of a header file and a prototype. Now I want to use V…

Then this does not seem supported. Doing a main.ino of void setup() { Serial.begin(9600); } void loop() { Serial.println("The var value is: " + String(someVar)); some_func(); delay(1000); } with second.ino as int someVar = 10; void some_func() { someVar++; } results in C:…

Actually, this does not work in the Arduino IDE for me either with the original main.ino and second.ino files shown above.

Can you show an example of multiple ino files with global variables in the style that you do?
