No more USB cable, messing with power and timing values. Arduino + MotorShield + ScrewShield + train + hall effect sensor + two magnets = fairly precise stopping.
Thanks for posting Limor. Your MotorShield rocks.
Turns out, the train is probably slower to get going in reverse because the brushes were worn in one direction for many years. That’s what you get for being cheap and basing your project around a used 1960s S gauge train!
