Hi, I'm currently working on a small project for my young nephew. This involves a section of track with rollers geared to work with a small DC motor. Now, here is the tricky part - I need a switching system which will detect a small toy car being placed at one end of the track and engage the motor to roll the car to the opposite end of the track. I want this to work the opposite way also i.e. so that the car placed on the far end of the track trips a switch which reverses the motor and rolls the car along to the other side. I am not too good with electronics but eager to learn so any help would be much appreciated. Thanks
