— Find your C:\Users\YOUR_USERNAME\Documents\LTspiceXVII\lib\ folder — Place pot.asy in your “sym” folder. C:\Users\YOUR_USERNAME\Documents\LTspiceXVII\lib\sym\ — Place pot.sub in your “sub” folder. C:\Users\YOUR_USERNAME\Documents\LTspiceXVII\lib\ sub\ — Click the text tool. Select “SPICE Directive” and paste in .include pot.sub. — Restart LTspice — Creat a new schematic. Press F2. You should see “Pot”.
The wiper is on a 0-1 scale. 1 = 100%. 0.5 = 50%. There is a glitch that occurs if a resistor is 0 ohms in LtSpice. So, this pot actually is limited from 0.001 – 0.999 so don’t freak out if your values are off by 0.1% on extreme settings.
This episode had no big theme, but many small ones.

Does the Arduino programming language have any place in professional products? This is a topic that comes up frequently for people that have a cool idea and feel the pull of product design but feel like maybe they are wimping out if they were to choose Arduino over Embedded C. Embedded C certainly has performance benefits, but that comes with costs of its own….TIME! In this podcast, I rant and rave incoherently about when Arduino programming should be used and should not be used when developing a product. I also talk about wool socks, heating pads, and dinosaur eggs.
The creators of the Arduino IDE made decisions to “simplify” their software. Essentially, they designed the Arduino IDE to have minimal barriers to entry on the first use. Unfortunately, this omits features that would be critical to almost anyone on their third use of the tool. In this episode, I ramble about why I love the PlatformIO IDE for VSCode when programming on the Arduino framework.
Last week I raved at just how much I love the STM32 Blue Pill. It’s my favorite microcontroller! Well, we have a new contender. Will the Raspberry PI Pico knock the STM32 Blue Pill from its pedestal? Find out in another action-packed Electron Injection Podcast episode. (rolled eyes)
