Using PWM outputs with an Arduino and a LED

Using PWM outputs with an Arduino and a LED @ The Custom Geek. Jeremy writes…

Hi everyone, been a while since my last post, but I have been a busy new daddy. I wanted to demonstrate what PWM output was and how to use it nicely in a sketch. I’m really big on ramping lights on and off (my entire house is set up that way) and would like to share how do accomplish that. I also wanted to use a video to show PWM outputs on a scope to help me explain the process.

  1. Thsnks for the pwm tutorial. Nicely done. One question though: where did you get the nice small scope?

  2. I had the same question about the scope. Seems like it would be nice for experimentation. Also, that was interesting to know about the PWM. I am a beginner and never realized how it worked exactly.

  3. I believe that is a Seeed DSO Nano:

  4. That looks right, thanks.

  5. Hi guys, thanks for the kind words! I have received a lot of questions about that scope. It is a DSO Nano v2 from seeedstudio, and I’ll be putting up a video on how it works in the next day or so at http://thecustomgeek.com.
    Thanks!
