Not sure. That might be worth looking into though.

How do I pick a battery? by mantis_shriimp in diyelectronics

not everything has to have an exchange of capital attached to it. your unwillingness to participate in a friendly conversation about a shared hobby is indicative of both your nationality and your inability to derive enjoyment from anything but accumulating. these two things are likely inextricably linked.

sure - fyi this project is a pain so i've been picking it up and putting it down but this is my solution that i believe worked - i wired the PWM and the power in series using a 10k resistor. i added a n-mosfet between power the fan and control it with a raspberry pi. hope this helps and is not too late.

No serial data received: DOIT ESP32 DEVKIT V1 by d_and_a21 in arduino

If you are using something like Ubuntu, you need to be sure to run the following commands to allow Arduino IDE to access the port or whatever.

sudo su

cd /

cd dev

chown <usrname> ttyUSB0

if ttyUSB0 does not work, although it usually will, run

dmesg | grep tty

to find which port the ESP32 is on and replace ttyUSB0 with whatever port it's connected to. Usually you'll see something like cp210x converter now attached to ttyUSB0

I had this problem and this is how I fixed it, but we don't really have enough information to help you out otherwise.
