(Apologies for my plebeian question to all EEs here.) Is there software that would tell me what I need to buy to make this [Arduino QT Py] work with [this specific set of 200 IC LEDs]? Alternatively, how can I check if a specific combination of components would work together? I spent a few hours with Flux and EasyEDA, but didn't get far.

I suggest a thorough discussion with GPT-4, based on datasheet information of the given parts, to talk through options for interfacing and then attempting to flesh them out and find concrete parts.

I'd rather ask at a specific forum, e.g. https://electronics.stackexchange.com/ https://electronics.stackexchange.com/

You are in luck Flux.ai does that…have a look at this tutorial https://www.youtube.com/watch?v=Y56AqPOjp0k&t=366s https://www.youtube.com/watch?v=Y56AqPOjp0k&t=366s Flux Copilot will happily assist you going from an idea to selecting the right components all the way to manufactured board!

Hey! I can't see your links to the LEDs or the QT Py, but I'm assuming they're probably neopixels as you mentioned "IC" LEDs. Drag your parts into flux and just ask copilot how to connect them together properly. Just to speculate on your project, you probably want some sort of gate buffer for the neopixel signal. And just ensure whatever power source you are using (be it a 5V source or a battery or buck boost converter) can handle the total current draw of those LEDs. I believe they have a wide operating voltage, but also just double check that if you are using a constant voltage source (which you probably are), it isn't over the maximum forward voltage of the LEDs. You can ask in detail with copilot by the way! Just wanted to echo some more resources to get you oriented. The second video shows actual examples of how to leverage copilot in your exact scenario.

  Thanks for your reply, Mark! The challenge for me is that the parts I'd like to use are not in the Flux library (or I can't find them). If I understand correctly, I would need to add them manually. To make sure I can use your simulator to check if all parts would work together, I would have to write some code, which is, sadly, way above my skill level. (I am fine with writing code, I just don't know enough about this domain.) I do like the Copilot feature, but, based on your video, it seems that I would need to add some properties that I don't much about. Just to be clear, Flux looks great, but it is perhaps for more advanced folks than me. Regarding my specific project, I would like to use: 1. Adafruit QT Py ESP32 Pico - WiFi Dev Board with STEMMA QT - 8MB Flash 2MB PSRAM (ESP32-PICO-V3-02): https://www.adafruit.com/product/5395 https://www.adafruit.com/product/5395 2. BTF-LIGHTING WS2812B IC RGB 5050SMD Pure Gold Individual Addressable LED Strip (one or two strips): https://www.amazon.com/gp/product/B01CDTECSG https://www.amazon.com/gp/product/B01CDTECSG I also figured out that I should probably use: 3. Adafruit NeoDriver - I2C to NeoPixel Driver Board - Stemma QT: https://www.adafruit.com/product/5766 https://www.adafruit.com/product/5766 I haven't found these components in Flux.

You need to study some EE to underestand what is going on. May the magic smoke be with you. /s
