View Arduino Mega 2560 Pwm Pins Photos. I tested it using simple code on the arduino ide. There are pin mappings to atmega8 and atmega 168/328 as well.
It comes with more memory space and i/o pins as compared to other boards available in the out of 54 digital i/o, 15 are used for pwm (pulse width modulation).
Pwm just adjusts the duty cycle of a square wave alternating between 0v and +5v so. The hardware connections are ok; The arduino mega 2560 is a replacement of the old arduino mega, and so in general reference, it will be called without the '2560' extension. One additional feature of the arduino mega is that this board also has.
