410 RGB LED Matrix & ESP32: Power delivery and testing

INFO:
Previously, I connected an ESP32 to my matrix and learned how to drive the LEDs. This time I'm correcting the power delivery so the matrix would shine as bright as a diamond.

In the video where you are using your breadboard, you have three wires hooked up to the ESP32 Dev Board. But in the schematic illustrated at 2:22 you have 4.
Which pin on the ESP32 board do you hook up the yellow lead that runs from the switch?

[@notenoughtech]

The initial colour test was done without the button. If you want to add a physical controller you will need an extra pin (or more) to map your input It was mapped to pin2 if I can trust my memory. I will have an article about building the panel soon as I came back to this project recently

Hi!
Can i do this but with 2 LED matrices more using the same circuit.. i mean connected to different pins?
Thanks for the video.

[@notenoughtech]

Yes you can this is all driven by a single wire per strip

[@prinschoco]

Hey, when will you add part 2 :p I am waiting already 2 years .

[@notenoughtech]

the time flies and I got distracted hah sorry :D

[@prinschoco]

@@notenoughtech No problem, thank you for actually answering my question ;) and keep up the good work with your channel!

[@notenoughtech]

I have a very cool use for LED matrix but I need the lockdown to end so I can work on it

[@colmslattery7094]

What soldering iron do you use?

Cool.....
Reminds me local Colorado marijuana growers making their own grow lights from Cree leds......

[@notenoughtech]

+Scar Hole haha that's one use of it! Never thought of that one :)
