You help would be greatly appreciated. I had a dead short between the driver pcb and the sensor shield. Larger motors have much stiffer torque v. Here ekyes the connections: TomGeorge Design and Repair of industrial control systems.

I tried exactly what you said and nothing happens…… hmm….

I have salvaged a printer head assembly from an old HP Deskjet Everything runs on smoke, let the smoke out, it stops running Thank for for comment John1a, i just tried but still did not work yet. The motor is ok move the head on either directions but only when I reverse the polarity manually.

Hi Feiticeir0 I have very little experience with arduino and only used kejes. This doesn’t give as linear or regulated speed control ll298 synchronous drive PWM on both top and bottom switches in anti-phase.


I if still in warranty, change it! For the power supply to the Arduino, the motor driver has a built in 5V supply right? I’ve been recently trying to apply PWM to control 3 6V dc brushed motors with two keyes L motor drivers and arduino uno. Motor driver can control only with arduno? Have you worked with these models before? I have all mechanical components ready I only need arduino sketch.

You need to program it for it to work. I will search if is possible, but probably you could just get: You will have to program into your sketch a minimum starting PWM, rather than relying on zero pwm to ramp up from.

If I only had to connect one stepper motor I would be fine. I do really appreciate it. I will really value your help.

BUT, I need to connect three stepper motors. Lower values will just not work. When the supply voltage exceeds 16V the power regulator located on the L could heat enough, then you need a separate 5V logic supply. You can see this post and understand it better: The driver can handle it! The connections on the board are fairly simple to understand: It can also let us drive two independent DC motors, controlling the speed and direction of each one. But I get stressed and walk away for awhile.

Does the code upload to Arduino without any problem?


Well, by your last comment, you may have a busted H-bridge. I suppose you kejes have finished your project, A look here could help to clarify this point http: There’s a minimum 2V drop through themore of a drop at higher currents.

But this is the problem: 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.

Do you know if you have to take off or leave on the jumper for the 5V mode while powering the driver with external source? Thank you for the comment, but I still have a lot to learn.

Can you please help me out? Leave a Reply Cancel reply. This is driving me batty. Your second post is right. Why would you want to do that?
