- || |
- || | A Wiring (and Arduino) Library, for Atmel AVR8 bit series microcontrollers,
- || | to produce PWM signals on any arbitrary pin.
- || |
- || | It was originally designed for 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).
