|| |
|| | A Wiring (and Arduino) Library, for Atmel AVR8 bit series microcontrollers,
|| | to produce PWM signals on any arbitrary pin.
|| |
|| | It was originally designed for use controlling the brightness of LEDs, but
|| | could be adapted to control servos and other low frequency PWM controlled
|| | devices as well.
|| |
|| | It uses a single hardware timer (Timer 2) on the Atmel microcontroller to
|| | generate up to 20 PWM channels (your mileage may vary).
