I have read many post regarding L298N + stepper + arduino and I am still lost...
I have several hydrid-stepper-actuators http://www.haydonkerk.com/LinearActuatorProducts/StepperMotorLinearActuators/LinearActuatorsHybrid/Size23LinearActuator/tabid/82/Default.aspx
and so far I am not able to use them because I am totally lost.
This is my current wiring (I'm using sparkfun's L298N breakout board):
OUT1 -> Stepper wire 1 (red)
VS -> power supply (5V, 3A in my case)
ENA -> 5v (arduino)
GND -> GND (all GND tied together)
CSA -> GND
OUT2 -> Stepper wire 2 (red-white)
IN1 -> Digital pin 2
IN2 -> Digital pin 3
VLS -> 5v (arduino)
ENB -> 5v (arduino)
OUT3 -> Stepper wire 3 (green)
CSB -> GND
IN3 -> Digital pin 4
IN4 -> Digital pin 5
OUT4 -> Stepper wire 4 (green-white)
I know that if:
Input1 = input2 : motor should stop .
Input1 =/ input 2: motor should turn on way or the other.
what I don't know is:
1.Which pins should go to PWM? (I assume all the inputs...)
2.A simple code to move CW, CCW and STOP. (the one that I wrote did nothing)
3. How do I count steps
4. Where to put the diode
