Programming Help: Move Straight, When Limit Switch, Back Up and Turn Around

Projects General Guidance

Hi folks.

I am trying to program a robot to move straight, and then when it bumps into something like a wall, I want it to back up and turn around. Then continue moving straight.

I am familiar with RobotC but this is my first time trying to program with Arduino software and I'm pretty much lost.

Any help is much appreciated. I attached the program below... but I'll also copy/paste it here:

#include <ArduinoRobot.h>
int limitPin = 8;
int LmotorPin = 1;
int RmotorPin = 4;

void setup()
{
Robot.begin(); //initalizer
}

void loop()
{ if (digitalRead(limitPin) == 0)
{
Robot.motorsWrite(200, 200);
}
else
{
Robot.motorsWrite(-200, -200);
delay(2000);
Robot.motorsWrite(200, -200);
delay(2000);
}
}

Thanks!!

Your choice but I thought you wanted help, seems I was wrong.
