best tutorial ever. arduino is the best!

[Znkank]

I was looking for this and a helpfull video again from you. Ty.!

[turkeykaiser]

Awesome, exactly what I was looking for.

Hello, AWESOME VIDEO!
Wanted to ask about the motor ratings used in this video

[subarutan]

Sir do you have a esp32 project that will auto reconnect for example the supply of esp32 turns out then it automatically reconnect?

[TomAHawk-pyvj]

Any plans on using power saving ESPNow instead of server/client via a permanent WLAN connection?
Maybe using two or more ESP32 to control each other that way?

[muhammadahmed]

Salam..
I taken all steps according to your instructions but when I
Installed the code the show error can u fix it. For md

[austinkerry]

Is the relay module esp32 and 2 the same 5v input supply ????

[hrvojekolar]

Great video! Does esp32 have enough memory for controling both relay for dc motor and one servo motor over wifi? Thank you!

[Znkank]

Can you add speed controll or a bar for any different parameter such as pwm to the control page?

[jaso]

the output from the relay is very low....my input was 12 v 2 A and directly connected the motor runs very fast....but when it goes through the relay the motor turns slow...is there any way to fix it?

[blackdiamond]

Great stuff, this helps a lot with a project I am working on.

However the code seems to be broken, I've tried accessing from computer and phone and both times when I paste the copied code as is I get errors when compiling.

For example in the section where it includes the 4 libraries the code only says:

#include
#include
#include
#include

After typing the 4 libraries manually I get other errors from other sections of the code. Please reupload or have an option to download the code as a file instead of copying and pasting.

Thanks

is the ESP32 compatible iwth 5ghz? or only 2.4?

[irshadirshu]

Why don't you add the circuit diagram?
