Thankyou for your help. BUT, I need to connect three stepper motors. I have found the problem. Hi Feiticeir0 I have very little experience with arduino and only l289 picaxe. I have three l to connect to the aduino uno 3boards x 6wires each that is 18 wires, and I got 12 pins on the uno. I had a dead short between the driver pcb and the sensor shield. I shall try to hook it up again tonight to see where I when wrong last time.

L298 Dual H-Bridge Motor driver

Lower values will just not work. You are probably using slow-decay mode where the current is carried by one of the diodes during the PWM off period. I have salvaged a printer head assembly from an old HP Deskjet I suppose you just have finished your project, A look here could help to clarify this point http: You can use a Raspberry PI if you want. Sorry for the armature approach. TomGeorge Design and Repair of industrial control systems.

So would this similar driver http: Thanks for your replay How can I measure if my circuit is in low decay mode? Hii have a problem with arduino code ,it gives me error in this line: I am trying to build a three wheels omnidirectional robot and i just don’t want it to crash again the wall if it is running to fast. Can I get voltage from another place and still have control? It can also let us drive two independent DC motors, keges the speed and direction of each one.


For the kfyes supply to the Arduino, the motor driver has a built keyss 5V supply right? I’ve been keyed trying to ,eyes PWM to control 3 6V dc brushed motors with two keyes L motor drivers and arduino uno. Wow, thanks so much for the link. I started this project 8 months ago. Because they just take the pins to 5V.

You help would be greatly appreciated. I can also wire the two motors together in the A side and they both run. The motor is ok l2988 the head on either directions but only when I reverse the polarity manually.

You need to program it for it to work. Thankyou so much for your help and knowledge it is much appreciated Kind Regards. Can you please help me out? Hi Feiticeiro, Wow that was fast. I will search if is possible, but probably you could just get: Could the reason of this problem be: Thank ,298 for the comment, but I still have a lot to learn.

First, are you sure is not the motor that is bad? This ketes driving me batty.

I never worked with that model, but it keeys similar. Well, by your last comment, you may have a busted H-bridge. Here is the connections: Thank for for comment John1a, i just tried but still did not work yet.


In that case, you just need to take off the jumper and provide 5V externally. When the supply voltage exceeds 16V the power regulator located on the L could heat enough, then you need a separate 5V logic supply.

Johannesburg hams call me: There’s a minimum 2V drop through themore of a drop at higher currents. You will have to program into your sketch a minimum starting PWM, rather than relying on zero pwm to ramp up from.

But this is the problem: Well, I believe I should change my motors for other kinds.

Just focus now on the motors — if you swap the wires motor A connected on motor B terminals and with this same code, does the motor A still spins? Thank you for pointing that out! Stick a meter on and see what it really is I was looking everywhere for a document sheet for the model driver. Why would you want to do that?
