hi
i download codes from below link:
and so complete wire the circuit to nodmcuesp8266 and relayboard.
after upload program to board see this :
this is mean that don’t complete load the program?
this is mean that don’t complete load the program?
Sure looks like a library issue to me.
Do you have the Blynk library installed? Which version?
Have you added the esp board support for the Arduino IDE?
The error messages, from what we can see, sure speak to a library/board support issue.
Set the baud rate to 115200 or 78400 to see the serial output properly.
Copying and pasting the whole compiler message would also be useful, rather than just screenshotting the last two lines.

As @Madhukesh said…
Pete.
by 115200 and 78400 is the same as 9600 in com3(serial output)
do you have any sugلestion؟
About what?
Pete.
that is for 115200 baud rate
If you disconnect the wire attached to pin D3 then reboot the NodeMCU does it behave any differently?
Pete.
i disconnect wire to pin D3. AND ONE MORE DISCONNECT D3 & SD3 BUT IS THE SAME LAST ERROR
Acording to this site . can i connect D3 & SD3 to +5v ?
It’s not an error, it’s the boot message from the NodeMCU.
But, after booting, the NodeMCU is not entering Run mode.
Try disconnecting everything except the USB cable.
Pete.
