Im trying out the code found here , let me quote the section of code that bothers me.
// set pin numbers for switch, joystick axes, and LED: const int switchPin = 2; // switch to turn on and off mouse control const int mouseButton = 3; // input pin for the mouse pushButton const int xAxis = A0; // joystick X axis const int yAxis = A1; // joystick Y axis const int ledPin = 5; // Mouse control LED
xAxis is a variable that is defined as an integer , however, it is being assigned a character(A0), How is this possible? I tried to compile and run the code and everything works well. I'm quite surprised!
