Arduino libraries use internal code, generically called the "core", to define the available I/O pins on a given Atmel microcontroller, assigned by pin number. For example, the Atmel ATMega168 physical ...

The Arduino Uno, operating with a 16-MHz clock, is programmed to use Timer0 to set up the PWM output OCRA at 244 Hz with the pulse-width set to 224/255 cycles. Figure 2 shows the waveforms when ...
