I was trying to run stepper motor from my raspberry pi model 3 B. I used the following tutorial -
I have followed various other tutorial also but not succeed in any. My connection are these -
My stepper motor is Nema 17 bipolar stepper -
My battery is Lipo battery of ratings - 11.1V & 2200mAh
Problem- Nothing in stepper motor is showing response, no movement nothing.
Checked- when i give voltage to either coil of stepper motor it shows a little deflection implies stepper is working correctly.
The most basic thing is not working like when i put 5V in IN1/2/3/4 i get 0.1V in all the outputs.
Where am i wrong??
