this is my first question here. I hope I don't mess it up.

I made a WiFi controlled LED strip about a year ago. The LED strip is one of the "dumb" (no individual pixel control) 12V ones and I used a Wemos Mini to control it. Now, I want to make a another one, but I can't remember why I chose the resistor values I did. Does the following look right?

Wiring Mock-up for WiFi LED Strip

The MOSFETs are 40T03GP. I tried googling, but I can't find a setup similar to mine to compare it to.


If you are using mosfets you can get rid of those 220ohm resistors. And if you are sure that your ESP outputs always are going to have a determinated logic state (0 or 1) even you can delete the 10k pulldown resistors. Remember that fet transistors does not require current but voltage

  • \$\begingroup\$ Thanks. The outputs are going to be analog write signals (between 0 and 1020) depending on the color desired, so I still need them right? \$\endgroup\$ – makerws May 28 at 3:11
  • \$\begingroup\$ does that outputs have a DAC? or the analog write is a PWM signal? \$\endgroup\$ – Oscar Andres May 28 at 4:04
  • \$\begingroup\$ I'm not really sure. In my code I am using analogWrite, but after a little googling, it looks like the Mini only has one analog-in pin, and no analog-outs (really not sure about this though). So, I think the analogWrite function might actually be sending a PWM signal. \$\endgroup\$ – makerws May 28 at 4:22

    \$\begingroup\$ tried it again without all the resistors. Everything works. Cheers \$\endgroup\$ – makerws May 28 at 13:26
