I am after a circuit schematic and parts list with functioning explanation on a Driver Circuit ULN2003a that will be incorporated into a type of remote control car that will allow it once switched on to trace parallel white lines...
Please help.. as i'm a numty.. i did this project years ago and now can't seem to find the schematic nor the parts list for it.. all i have is a brief on how i went on to devlop it :( (which is usless without knowing the othe rinfo)...
i was and am hoping you all out there may have come across soemthing like this before.. and can help me out.... the circuit was given to me by a lecturer years ago and hence i think that it will be in the public domain that other electronic minded peeps would have seen....
thanks to the guy that sent me a mail link, on the one that traces black lines..
regards
