High frequency PWM signal
Use and Arduino Uno microcontroller board to generate a variable frequency variable pulse with PWM signal . The output pulse width should be adjustable , you can use an analog pin voltage varying from 0-5 V for duty cycle control (0 V should correspond to 0 duty cycle and 5V should correspond to 100% duty cycle). The frequency of the signal should range from 10kHz to 20 kHz and should be programmable .
i have a problem with the frequancy part, what i shloud do !
