Description: PWM function of the requirements of the experimental use PIC16F877A CCP1 module and a first-order RC low-pass filter to produce a 5Hz sinusoidal signals. The observation frequency sinusoidal signal with an oscilloscope for accurate 5Hz, and no obvious distortion. Readers without conditions by observing directly and CCP1 output pin connected to the LED flashing frequency to determine the frequency of the sinusoidal signal.
