You can adapt in your sketch a driveMotor int dutyCycle funtion that does the following: This is driving me batty. You will have to program into your sketch a minimum starting PWM, rather than relying on zero pwm to ramp up from. Any comment will be truly appreciated. I tried exactly what you said and nothing happens…… hmm…. For the power supply to the Arduino, the motor driver has a built in 5V supply right? And if you connect the motor B on the motor A terminals, does it spin?

Well, I believe I should change my motors for other kinds. I can run the other motor strait off a battery, the A side runs well and also changes direction when the sensor is made. Why would you want to do that?


Larger motors have much stiffer torque v. You need to program it for it to work.

I can also wire the two motors together in the A side and they both run. Lower values will just not work.

The motor is ok move the head on either directions but only when I reverse the polarity manually. First, are you sure is not the motor that is bad?

Can I get voltage from another place and still have control? Here we have several keyds for the motors from left to right: Johannesburg hams call me: I suppose you just have finished your project, A look here could help to clarify this point http: Hi Feiticeiro, Wow that was fast.

Leave a Reply Cancel reply. This doesn’t give as linear or regulated speed control as synchronous drive PWM on both top and bottom switches in anti-phase. Thankyou for your help. I got it work!

L298 Dual H-Bridge Motor driver

I if still in warranty, change it! I was looking everywhere for a document sheet for the model driver.

Your second post is right. You are probably using slow-decay mode where the current is carried by one of the diodes during the PWM off period. I shall try to hook it up again tonight to see where I when wrong last time. You help would be greatly appreciated. Stick a meter on and see what it really is BUT, I need to connect three stepper motors. I started this project 8 months ago. TomGeorge Design and Repair of industrial control systems. Hi Feiticeir0 I have very little experience with arduino and only used picaxe.

Hii have a problem with arduino code ,it gives me error in this line: I have found the problem. Wow, thanks so much for the link.

Please read the post in the above link!

LN Motor Driver Board – Geeetech Wiki

I did not have much knowledge about motors or motor drivers before I started to built it Thanks for your replay How can I measure if my circuit is in low decay mode? 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. Motor driver can control only with arduno?
