"Simplicity is a great virtue but it requires hard work to achieve it and education to appreciate it. And to make matters worse: complexity sells better"
No more USB cable, messing with power and timing values. Arduino + MotorShield + ScrewShield + train + hall effect sensor + two magnets = fairly precise stopping.
Try Adafruit's new iPhone & iPad app for makers! Circuit Playground!"Incredibly handy for anyone working in electronics. Perfect for engineers and non-engineers alike."
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!
