I will really value your help. BUT, I need to connect three stepper motors. It keyed also let us drive two independent DC motors, controlling the speed and direction of each one.

LN Motor Driver Board – Geeetech Wiki

Everything runs on smoke, let the smoke out, it stops running You help would be greatly appreciated. Can I get voltage from another place and still have control?

I will search if is possible, but probably you could just get: Thanks for the tutorial! Hi Feiticeir0 I have very little experience with arduino and only used picaxe.


The driver can handle it! Hello feiticeir0 Ok its pretty clear you know the stuff well. Larger motors have much stiffer torque v.

Have you worked with these models before? Sorry for the armature approach. Does the code upload to Arduino without any problem?

You will have to program into your sketch a minimum starting PWM, keyess than relying on zero pwm to ramp up from. Is this even possible?

Thanks for your replay How can I measure if my circuit is in low decay mode? And if you connect the motor B on the motor A terminals, does it spin? Hi Feiticeiro, Wow that was fast. Here is the connections: But the Keyes l has en a-b. I have all mechanical components ready I only keyse arduino sketch.

Could the reason of this problem be: This doesn’t give as linear or regulated speed control as synchronous drive PWM on both top and bottom switches in anti-phase. Please read the post in the above link! Well, I believe I should change my motors for other kinds. You can see this post and understand it better: This is the sketch I used. Here is my request. Thank you for pointing that out!


If you continue to use this site we will assume that you are happy with it. In that case, you just need to take off the jumper and provide 5V externally. Well, by your last comment, you may have a busted H-bridge.

L298 Dual H-Bridge Motor driver

I do really l98 it. When the supply voltage exceeds 16V the power regulator located on the L could heat enough, then you need a separate 5V logic supply. Your second post is right.

Keye, thanks so much for the link. Here we have several connectors for the motors from left to right: Stick a meter on and see what it really is I did not have much knowledge about motors or motor drivers before I started to built it But I get stressed and walk away for awhile.

Will you help me writing such a program?
