So up front, I'm not good with arduino yet I want to try this project out. I saw this video Making My Own Version of Nanoleaf Aurora - DIY Project - YouTube, and instantly wanted to make it. It checks the boxes of being easy to control via Blynk app on my phone and seemingly simple to recreate. I bought all the parts, 3d printed the hex's and started testing.
Problem is none of it works. When I have the level logic shiftier connected per the wiring diagram (https://imgur.com/a/Zbh80aO), the arduino won't boot. If I take it off, it boots. Ive tried with the LLS, without it. I've tried on a ESP32 and an ESP8266 and I am just hitting a wall after about 15 hours of messing with this. (2 extreamly long nights)
I'm using 12v WS8211 LED strips as per their build guide.
So tell me this, is the project borked from the begining or can this actually work?
Please read the how to use this forum sticky post. It will tell you how to ask a question, and how to post images as an attachment, I will not go to that site you linked to as it infects my browser with unwanted cookies.
In order to help we need to know exactly what you have done, your post is not telling that in any sort of detail to be useful. However it does look a very big project to tackle for someone who is new to this sort of thing. Look at how the child in the video struggled to get it to work, he didn’t fill me with any confidence he knew what he was doing.
That circuit diagram is not suitable - but not harmful. You must have connected it wrong.
Why not suitable? Well, that is the wrong sort of level converter. What you need is simply two gates out of a 74HCT14 connected in cascade (with the other four gates inputs connected to ground or Vcc if you have no other use for them). But if the ESP is failing to boot, you have miswired a short circuit across it - likely across the 3.3 V pin.
