Hello
My name is Sri. I am working on a project to build automatic frequency tuning and impedance matching network for antennas using arduino. i am a ham radio enthusiast and this is my effort to tune and match all my antennas automatically.

I would like to know if any of you have used digital pins of arduino to drive PIN diode?

FIRST YOU USE PWM PIN FOR BISEING OF PIN DIODE AND WHAT IS THE FREQUENCY  OF YOUR APPLICATION

Hello I am KF6THI, no longer active! The answer is yes all will drive LEDs but stay under 10 mA if possible.  I would suggest getting an arduino cookbook, and read it while waiting for reply's to your QSLs, it will a very valuable assert to your shack.  There are several PWM pins that can modulate the pin diode. This response is to help you get started in solving your problem, not solve it for you.
Good Luck & Have Fun!
