Can anyone help me with connecting node MCU with big motor shield
Which shield? Which power supply?
normal motor shield which we use for arduino…i need to connect with node mcu
The physical pins on the Node MCU will be different than the physical pins on the Arduino (I assume you mean UNO?).
However the GPIOs assigned in your sketch will remain the same.
You need to connect the relevant pins from your shield to the appropriate pins on the Node MCU.
ie:
Arduino UNO Pin 2 is mapped to GPIO 2
NodeMCU Pin 2 is mapped to GPIO 4
Once you match the correct pins your sketch should work.
