The AVR MCU just doesn’t have a whole lot of memory available for program storage and variables, and many of the AVR parts don’t have any way to add more. That being said, the ATmega32 and ATmega128 types can use external memory, but then the I/O functions for those pins are no ...
Whenever you have some code that you need to monitor, you can use the Serial print() method to allow you to check the values of variables or the execution of code and see those messages in real time using the Serial window of the Arduino IDE. Use the begin() method of the Serial ...

these variables and constants control the flow of the program indirectly. This write-up is a brief explanation of the scope of variables and constants. The types of scope of variables are also discussed. Furthermore, to illustrate the scope in detail the example code for variables and constants...
On line 3, you'll see a new structure: we call this anarray.An array is basically a list of variables, in this case, it is a list of variables of the type int. We use square brackets to indicate that it is an array. To initialize the array, we use curved brackets, and the val...
