This is driving me batty.

You can see this post and understand it better: Larger motors have much stiffer torque v. 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. Lower values will just not work.

I got it work! If you continue to use this site we will assume that you are happy with it. I started this project 8 months ago. Motor driver can control only keyew arduno? I suppose you just have finished your project, A look here could help to clarify this point http: The driver can handle it!

I if still in warranty, change it! You need to program it for it to work. So at low PWM average voltage, less the drop which depends on the current drawn, there may be very little left at the motor.

I had a dead short between the driver pcb and the sensor shield. The reluctance to start at drive level despite it working at that drive level from full speed is partly a result of static friction, note, you will often see this kind of jeyes in motor function driving real frictional loads with small motors.


LN Motor Driver Board – Geeetech Wiki

Thanks for your replay Tom. This doesn’t give as linear or regulated speed control as synchronous drive PWM on both top and bottom switches in anti-phase. I will really value your help. Well, I kryes I should change my motors for other kinds. I do really appreciate it. You help would be greatly appreciated. First, are you sure is not the motor that is bad?

But I get stressed and walk away for awhile. This site uses Akismet to reduce spam. There’s a minimum 2V drop through themore of a drop at higher currents.

I have found the problem. Hi Feiticeiro, Wow that was fast. Leave a Reply Cancel reply. And if you connect the motor B on the motor A terminals, does it spin? Thanks for your replay How can I measure if my circuit jeyes in low decay mode? Hi Feiticeir0 I have very little experience with arduino and only used picaxe. No, this project does not include a joystick!

Thank for for comment John1a, i just tried but still did not work yet.

Why would you want to do that? But the Keyes l has en a-b. It can also let us drive two independent DC motors, controlling o298 speed and direction of each one. I can also wire the two motors together in the A side and jeyes both run. Everything runs on smoke, let the smoke out, it stops running Hii have a problem with arduino code ,it gives me error in this line: I can run the other motor strait off a battery, the A side runs well and also changes direction when the sensor is made.

L298 Dual H-Bridge Motor driver

Can you please help me out? It was a fluke but its going now. Sorry for the armature approach. I did not have much knowledge about motors or motor drivers before I started to built it I have all mechanical components ready I only need arduino sketch. I’ve been recently trying to apply PWM to control 3 6V dc brushed motors with two keyes L motor drivers and arduino uno.

When I apply a high PWM e. Hello, need to connect sparkfun 68 oz. Thank you for pointing that out! When the supply voltage exceeds 16V the power regulator located on the L could heat enough, then you need a separate 5V logic supply. Thanks for the tutorial! Can I get 2l98 from another place and still have control?

Could you help me and email me at dzeima hotmail. Here we have several connectors for the motors from left to right: If I only had to connect one stepper motor I would be fine.
