Hi everyone!
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).
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).
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.
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.
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...
Any thought, other than getting something with more IO pins?
Wow, you totally misunderstood the whole issue?
The point of China subsidizing their industry and their universities isn't so that their people can "buy a new car every year or two" because they're cheap.
It's because that way they progress their technology and manufacturing infrastructure so much that no one else can compete. They chase everyone else out of the market, while their companies pull in massive profits and keep the high paying jobs for their citizens.
Well paid workers can buy their own housing without government assistance, but what happened to all those tax benefits the US gov handed out for EVs? They catapulted Musk's wealth, while the workers are nowhere closer to affording an EV, or a home, or even healthcare.
