@madworm cheers mate  smiley-grin

@Pauls cheers.... for being a ****! yeah i did clearly need help hence the reason why i posted in this forum. not sure why you even bothered to comment? are you that much of a loser you go on electrical forums to unhelpfully reply to posts?

Moderator edit: personal insult diluted. Keep it civil.

Hi

I have been working in a project to create and drive a small vehicle to start from a point drive to a wall touch it and return to the same point.
My group and i planned on doing this by driving the vehicle from a 3v geared motor. also to measure the distance we used a slotted disk attached to the shaft which ran through an optical sensor. the plan was once the vehicle had travelled to the wall a micro switch on the end would reverse the polarity of the motor and send it back in reverse and match the distance recorded from the optical sensor.

At first we tried to achieve this by using and circuit of 3 up/down counters but encountered several problems. we have now been advised to use and program an arduino board and use a h-bridge to reverse the motors polarity. However we are all new to arduino boards and are quite rushed for time to get it done?

If anyone can give any help or give suggestions on how to achieve this it would be really appreciated!
