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.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  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!
