Hi,

I build the car. Recording such a video wasn't a planned stuff, we just said that "What'll happen if the car will mot work tomorrow at the presentation?" and recorded this for an "emergency case" : ) Thus, I'm speaking in Turkish but wrote a discription about what I've done in English also. Thank you all for you help : )

I forgot mentioning that the motor pulses for three time and I was adding it to my reply with a simple forward moving code and schematic of the driver circuit until I see you reply smiley  So the problem is happening from the reason you told. Changing the pin 13 with another one seems simpler than the second solution = ) Thank you both for you interests.

Hi everyone,

I use L298 for driving a Rover 5. However I experience an unwanted move from the left motor at start. It's a short movement but don't want this to happen anyway. I used pins 13 and 12 of UNO as the digital outputs for controlling the left motor. Can it be happen because of the pin 13 and it's onboard LED circuit? I'll be glad if you help me.

Thank in advance,

Thank you = ) At this point the encoders are excessive  -I guess- for me. I won't use them for my current project. Buying that 4 channel would be more convenient however I have've limited time and if a delay happens during shipping it won't be good for me : ) If I get stuck I'll get some help from the driver's schematic : )

Hi,

I'm wondering that what will happen when I use only a simple L298 ic for driving the Rover 5? Or in other words: Is it possible to drive it like this?

Hi everyone,

I'm kind of new to all this stuff and I'll be glad if you help me. I'm a senior electronics engineer student and my final project is about making "a light tracking vehicle". I decided to use an Arduino UNO for this project. There will be panel on the Rover 5 which can rotate in x- & y- axes. The panel should face to the light source and the mission of the vehicle is bring closer the panel to the light source. After reaching a determined voltage level, the vehicle'll stop. That's it.

Panel would have 4 light sensors on all 4 sides of it and with the help of voltage difference it will position it self to the light source (first it will look at the diffrence on the sensors which are on the horizontal line, the servo will turn to direction of the lowe leveled sensors until both sensors have no diffrence. This procedure is same for the ones on the vertical line.).

While searching for the "vehicle" part of my project, I come up with this Dagu Rover 5 and liked it very much. However I'not sure which model should I buy? I found 4 motored and 2 motored ones; I don't know which one is enough (If you ask me I would choose 2 motored) ? (I found 2 models of Rover 5 on hobbyking.com; one has 2 motor and 2 encoders and the other one has 2 motors and no encoders) And which kind of motors are they? Servo or DC motor? Also I don't any idea about that encoder stuff. What does it for? Is is useful or necessary for me? (I might have forgotten to tell you everything about my project, if I did please say and I'll explain)

Thanks in advance,

Ali Sercan KARTAL
