I'm trying to create a Arduino Nano based PWM generator. However, since the pins from the Arduino only can produce PWM signals up to approx. 1kHz (and I need mauybe 2-3kHz) my plan is to use additional components to create the PWM signal.
My idea is to find a single component that can be operated through Arduino and can generate an adjustable PWM signal. But I'm really having a hard time finding this type of module. For example:
This one can produce the wanted waveforms but has no duty cycle adjustment.
This one seems to be able to do everything I need but is not digitally adjustable through Arduino input.
Does anyone have suggestions on what module to use? Thanks!
