/diy/ - Do It Yourself

>>1735945
okay, so, i oscoped it and shit just got downright riddiculous

bottom pic is signal from the chip (fartduino) being in the breadboard where i tested it on my led strip spool and it works fine there, the leds light up, so i know that is how the signal is supposed to look

top pic is the signal from the PCB in the photo.
As you can see they are identical, so the signal is 100% correct and going into the led strip data pad, so why the FUCK isn't it working. I even oscoped the buck converter output to make sure there isn't any voltage drop or noise, and nope, the output takes less than 1ms to jump to 5V and then it stays there nice and clean, as expected.

So the strip is getting 5V, GND, and correct DATA sequence and yet... it's not fucking working.
I even probed the beginning and end of all 3 pads to make sure the traces in the strip aren't broken

pls help, i am about to drink my entire bottle of fecl3 because i can't take this anymore
