(arduino robot) Pleaz read it

i make self parking car with arduino robot. but how can the robot drive with 45 degrees???. i have this command " Robot.motorsWrite(255,255); "

You haven't provided anywhere near enough information to provide an answer

Please read and follow the directions in the "How to use this forum" post.

Do not cross post...other copy deleted.

AWOL:

It’s worse than that Jim! :astonished:

Or not Jim, but - pleas in subject headings tend to make it far less likely for people to offer assistance, even if the actual requests were themselves coherent.

Replace the 255 with 45, and you go from 255 degrees to 45 degrees.

Thank you for ur Answer and sorry for my question wich is so short and mybe is not clear. Arduino robot has just 2 wheels and is take just Robot.motorsWrite(255,255); or Robot.motorsStop;

as example:
#include <ArduinoRobot.h>
#include <Wire.h>

void setup() {
// initialize the robot
Robot.begin();
}

void loop() {
Robot.motorsWrite(255, 255); // move forward
delay(2000);
Robot.motorsStop(); // fast stop
delay(1000);
Robot.motorsWrite(-255, -255); // backward
delay(1000);
Robot.motorsWrite(0, 0); // slow stop
delay(1000);
Robot.motorsWrite(-255, 255); // turn left
delay(2000);
Robot.motorsStop(); // fast stop
delay(1000);
Robot.motorsWrite(255, -255); // turn right
delay(2000);
Robot.motorsStop(); // fast stop
delay(1000);
}

but i want the the robot reserves with 45 degrees .
can u help me?

What have you tried/

Not before you can explain what this is supposed to mean.

when i write " Robot.motorsWrite(-255, 255); " my robot would rotate to right. the problem i need that Robot does not rotate rather riserve with with 45 degree.
here is my full code

and plz if you know why my code doesn’t work exactly , plz tell me.

#include<ArduinoRobot.h>
#include <Wire.h>

#define minimum_CarW 20 // carwidth
#define minimum_CarL 20 // carlength
#define direkt 180

Swap the wires of the offending motor.

OK, first things first.

You need to go and read the forum instructions so that you can go back and modify your original posts (not re-post them) - using the “More → Modify” option below the right hand corner of your post - to mark up your code as such using the “</>” icon in the posting window. Just highlight each section of code (or output if you need to post that) from the IDE and click the icon.

In fact, the IDE has a “copy for forum” link to put these markings on a highlighted block for you so you then just paste it here in a posting window. But even before doing that, don’t forget to use the “Auto-Format” (Ctrl-T) option first to make it easy to read. If you do not post it as “code” it can as you now see, be garbled and is always more difficult to read.

It is inappropriate to attach it as a “.ino” file unless it is clearly too long to include in the post proper. People can usually see the mistakes directly and do not want to have to actually load it in their own IDE. And that would also assume they are using a PC and have the IDE running on that PC.

Also tidy up your blank space. Do use blank lines, but only between complete functional blocks.

thank you very much.
i will keep it and fix my post then i will post it in the right dipartment

the right dipartment

Which would be a reply to this existing thread.
