    On the first embedded circuit board I ever worked on, the vendor provided a demo by which the LED grew from off to on and back again gently. They did this by using a sine wave, and then mapping the output to the PWM controller mentioned above. At the time, I thought this was just awesome! Since then, I've discovered that a similar effect can easily be created from a triangle wave and that the sine function isn't needed at all. Now, I think any beginner should have fun creating a project similar to the "Knight Rider" effect from years ago: It's an easy and a fun project. Yours, Dan

    Hi Megaxoplasma, To control the LED intensity you only switch it on part of the time, using a technique called Pulse Width Modulation (a.k.a. PWM) If you switch the LED on and off quick enough, you are only able to see the average intensity. To avoid flicker you need to switch it at least on and off at least 50 times per second.

    Hello, Thanks for the response. I hope in the future that there will be a couple of tutorials released for designing Vivado and SDK. Best regards, J.
