(First of all, sorry if my english is bad, it isn't my native language)
I'm trying to replicate the following project to a college project:
Instead of using the same sound sensor, i was just able to find another one, so I'm using the KY-038.
I couldn't purchase the same LED strip, so I bought the WS2812.
When I turn this project, instead of running properly, just the first LED turns on green, the others don't turn on at all.
I tested the LED strips using others codes giving by the Arduino IDE and the entire LED strip is working fine, just have this problem when I try to replicate the project.
I'm totally new to Arduino, I'll appreciate the help
God yet another crap Instructables project! Again no schematic just a physical layout diagram which is great for mindlessly following but rubbish for actually conveying a circuit.
This one is trying to power too many LEDs from an Arduino’s 5V line, and it has no capacitor across each strip.
As this is your collage project, is it “only” reproducing what some one has given you instructions to follow, or would you actually be expected to think about things?
A bit like getting a LEGO Pirate’s ship set and following the construction instructions as opposed to building a Pirate’s ship from a whole bunch of LEGO bricks.
As an old fart it seems to me that nowadays education is all about learning to follow instructions, rather that actually learning stuff. Which it seems is all that the capital system wants from 99% of its work force.
So we need to see what sort of cockup you and that author has made of the project, so please supply:-
A photograph of your wiring
A link to the sound sensor you got as a replacement.
The software you ran.
A description of what you did to test this.
By the way the whole concept of this project is flawed, basically it will not work to tell when you need ear protectors as that depends on the nature of the sound not just the peak amplitude of a waveform.
