Hey someone knows how to activate nema 17 stepper motor with relay using arduino uno
No. That's not possible.
Welcome to the forum
Installation and Troubleshooting is for Problems with the Arduino IDE itself NOT your project. It says so in the description of the section. Therefore I have moved your post here.
You might want to look at this How to get the best from this from this Forum before you proceed any further.
Stepping motors need pulses, you can't supply them with relays as the relay can only switch at a very slow rate. NEAM specifies the size of the stepping motor fitting so tell nothing about the voltage and current needed.
