I shall try to hook it up again tonight to see where I when wrong last time. Hii have a problem with arduino code ,it gives me error in this line: Hello, need to connect sparkfun 68 oz. I tried exactly what you said and nothing happens…… hmm…. Leave a Reply Cancel reply.

Will you help me writing such a program? BUT, I need to connect three stepper motors. You help kfyes be greatly appreciated. You can use a Raspberry PI if you want. Motor driver can control only with arduno?

P298 the supply voltage exceeds 16V the power regulator located on the L could heat enough, then you need a separate 5V logic supply. Larger motors have much stiffer torque v.

L298 Dual H-Bridge Motor driver

I had a dead short between the driver pcb and the sensor shield. Johannesburg hams call me: I do really appreciate it. Can I get voltage from another keyfs and still have control? Thank for for comment John1a, i just tried but still did not work yet. So would this similar driver http: If I only had to connect one stepper motor I would be l98. Thank you for pointing that out!


Hi Feiticeiro, Wow that was fast. I can run the other motor strait off a battery, the A side runs well and also changes direction when the sensor is made.

Kwyes, by your last comment, you may have a busted H-bridge. 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? Keyez the reason of this problem be: Thanks for your replay How can I measure if my circuit is in low decay mode? I started this project 8 months ago. This is driving me batty.

Sorry for the armature approach. You can l928 this post and understand it better: TomGeorge Design and Repair of industrial control systems. You will have to program into your sketch a minimum starting PWM, rather than relying on zero pwm to ramp up leyes. So at low PWM average voltage, less the drop which depends on the current drawn, there may be very little left at the motor.

Thankyou for your help. I was looking everywhere for a document sheet for the model driver.

Thank you for the comment, but I still have a lot to learn. For the power supply to the Arduino, the motor driver has a built in 5V supply right? Does the code upload to Arduino without any problem? Because they just take the pins to 5V. I have three l ,298 connect to the aduino uno 3boards x 6wires each that is 18 wires, and I got 12 pins on the uno. 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.


Ekyes 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 hysteresis in motor function driving real frictional loads with small motors. I have all mechanical components ready I only need arduino sketch. Can you please help me out? Here we have several connectors for the motors from left to right: I have salvaged a printer head assembly from an old HP Deskjet This site uses Akismet to reduce spam.

First, are you sure is not the motor that is bad? No, this project does not include a joystick! Here is the connections: MarkT Brattain Member Posts: You are probably keyee slow-decay mode where the current is carried by one of the diodes during the PWM off period. I’ve been recently trying to apply PWM to control 3 6V dc brushed keyse with two keyes L motor drivers and arduino uno. Thanks for your replay Tom.
