Hi everyone!\n
\n
I’m trying to control a “dumb” led light strip segment with an ESP-01S. This is fairly low current, the strip will pull 150mA-200mA max (depends on… artistic? needs).\n
\n
I have two NPN transistors (2N2222), one to control the 12V supply to the white “channel” and the other the red+blue (don’t need the green).\n
\n
I had to pull-down the gates as I had some flickering, and it works perfectly if I manually connect the GPIOs **after** the ESP-01S boots.\n
\n
The ESP will boot if I have the RX pin (GPIO03) pulled down on boot, but not if I pull down any of the others.\n
\n
I’m not smart enough to come up with a way to have that extra pin I need to be high only during boot, while the gate it’s attached to needs to be pulled down…\n
\n
Any thought, other than getting something with more IO pins?
