I have this project where by we need to design a moving car made powered using motor. Currently we have made the car LED counts from 0-7 and back to 3 and up to 7 again as shown in the multisim file.
We are required to make the car travels from station 3,4,5,6,7 (made using U shape arcylic material at 15cm tall) and then pause and reverse to 3 once it reaches 7 . We need help on how to devise the circuit for the above part Thanks.

 

This is utterly confusing. What is the connection between whaterver the "car LED" is counting from something to something and a physical car powered by a motor moving along some U-shaped acrylic material? There just seems to be a huge gap in there somewhere.

You post a schematic (and thank you for that!), but say nothing about what the three switch inputs are for.
