Hallo

 

Just last week I build and tested a PWM RGB project on my Netduino, and yesterday I wanted to do something else so I made a new program and was ready for testing.

 

Hooked up my Netduino and deployed the program, Without errors.

But nothing happened!!

 

Tried a simple program (blinky) for testing. put a breakpoint in the program, and ran it again.

Nothing, not even a break.

 

After a second look I figured out that the program did not even start.

 

I flashed the firmware on the Netduino, tried it again, nothing.

 

 

Has Anyone encountered this problem before?

Hello,

I created the following circuit:

^{LED STIP = LED STRIP}

I’m chancing the duty cycle of the PWM to control the light output of the LED stip.

so in de code I’m setting the duty cycle to 0%.
but there still is a low voltage coming out of the PWM port,
so the PNP is still being triggered, and the LED will still emit light.

How can I fix this? so on a duty cycle of 0% the voltage on the Base of the PNP = 0V.
