Google 'Arduino Timer1' library.

Hi, I generate a PWM signal with ARDUINO UNO and I want to send from this Arduino to another, which is connected to a Buck converter...but I dont know how exactly do this...any idea?

If you're looking for a 20kHz PWM signal for a DC-DC reductor, you're way beyond being a beginner. Perhaps you're just looking for code?
