LED on pwm on arduino

Can someone give a example of lighting a LED on digital pin #9 as a pwm. My attempts seem to be coming up short. I have the the LED wire threw a resistor to ground and when I use the LED component macro it lights fine but on the simulation my pwm meter work like it should but in actual circuit not light from the LED. Thanks in advance . Bill

Hi Bill,
Can you attach your program so far so we can see what your trying and hopefully point you in the right direction. Otherwise we are guessing about your type of Arduino etc..

Sorry I forgot to attach it.

Hi Bill,
No problems here is a example that should ramp up the LED brightness and then ramp back down.

Thanks for the sketch. I still am not getting the LED to light with pwm .Do I need the LED to be connected threw the resistor to ground or to the 5 v? I can get it to work using the Arduino compiler in "C" but not threw the flowcode software.

Hello,
Sorry the example I gave had the PWM component set to the wrong output pin, it should now be on pin D9 as you stated.

Thank you , once again you have come threw and shown me how to do something in Flowcode. It works well. Now all I have to do is figure out how you decide which PWM pin get selected on this and I will be on my way. Thanks again, you guys never cease to answer a question that even I can wrap my head around it. Bill

LOL, now that was easy . I looked at your 1st example and saw in the properties menu where you list each channel of PWM and saw that they have a output pin associated with it and that I kept using PWM1 in my program which would then relate to $PORTD.6 . Lesson learned - thank you once again.
