Noise From Motors

Hi Guys,

 Some of you may remember that I was having a difficult time getting an Arduino Motor Shield to run my 4 wheel motors on my robot Herbert.  No matter what I tried, I couldn't get it to work right so I finally decided to try a different route.  I bought two qik2s9v motor controllers from Pololu...one board for the front motors and one board for the back motors.

Update!  I answered my own question....I found that this motor controller has a max PWM of 127 not 255.  Once I changed that, I was okay!


HI Guys,


Everyone's Favorite Motor Controller Board

Hi Guys,

I'm having problems with my Arduino's motor shield controlling my 4wd motors and I'm thinking about going another way.  So I was wondering what everyone's favorite motor controller board might be.  I need to control four wheel motors and I don't wanna spend more than 40 bucks or so at the most....

 Any ideas?

Hello and My New Arduino Robot Project

Hi Guys,

This is my first post here although I have been lurking for a few weeks now. I am brand new to the world of robots and Arduino. I bought my first Arduino in September and I'm just starting my first robot! My robot's name is Herbert...named after H.G. Wells and kind of an homage to Star Trek....

I plan to have Herbert be a long term learning project. I'm starting with simple motor control and moving up and onward from there. Here is my first video documenting my learning about Arduino motor control using transistor circuits:

Hi Guys,


I'm brand new here and I've searched the site and can't figure out how to post an avatar....any suggestions on where I may look?  I didn't see it under my account settings, nor did it come up when I searched the forums.  Hmmmm...
