It’s worth mentioning that declaring global variables isn’t an absolute necessity. However, it’s advisable that you declare your variables to make it easy to utilize your values further down the line. Every Arduino sketch must have a setup function. This function defines the initial state of the Arduino upon boot and runs only once
