usb LED strip randomly turning ON

>USB

Unplug it ?

If the USB is only for power (?) power it from a USB mains adapter/hub/device that does not contain sensitive information. Plugging in permanently powered rnd ali crap to your laptop, its not a long-term winning idea.

That chinkshit controller you bought is picking up a wireless signal that is similar or exact to whatever signal it is to turn on the strip. This is what happens when you don't control your own strip or buy chinkshit stuff.

Question though OP. Does it always turn on the lights around the same time, same color, same pattern? If not is it the last color and pattern you last turned it on to?

When you unplug it and plug it back in, does it turn on, turn off, or go back to whatever state it was in?

>>1202466
wow. how fucked I am, then?

>>1202475
will need to do some testing. I recall it turns out the last used pattern after remote shutdown. but the time seemed to be once a while.

>>1202576
it remembers the last used settings

Interesting. Does the color ever change on its own or turn off on its own while on?

Would be interesting to get an Arduino with an RF module, record the signals from the remote, then set the Arduino to watch for those signals. It's possible the remote is malfunctioning. Pull the batteries before you go to sleep tonight to see if that remedies it.

thank you for insights.
I've pulled the batteries out and let it off.
We'll see in a few hours;

okay. so I've pulled out the battery from controller and let it on table.

the led turned off after while.

I'll do some testing and record time it takes to turn off. If it's a set time interval, or maybe neighbor with strong TV remote?

I'll post details later

Typically TVs have IR remotes, but I guess some have RF remotes now. You know now that your remote isn't malfunctioning, so it's either the controller attached to the LEDs malfunctioning or it's getting a signal from elsewhere.

Is it the 1 meter version with 30 LEDs? Can you read the markings on the 3 SMD resistors close to the RGB LED? 5V*0.5A/30=83mW per LED, including series resistors. Bright enough as a night light.

I have both 1m and 2m version and both behave this way.
Pic related, the resistors on the first one. Marked with 101,151,101

Thank you. Interesting experiment. If you leave the battery out and the LEDs still turn on now and then it may be that someone else uses a similar remote control that uses the same on/off code. In this case you could reduce your receiver's sensitivity by wrapping some alu foil around it.
