First time Posting Need Some help with my Motor Control

Im building a replica Crane game using my Arduino mega 2560 for my BS in Electronics. I think i have most of the code down but when i connect everything up to my motor controller nothing happens. Can someone look at my code and let me know if I did something wrong. other sites i have tried havent really offered any help.

#include <LiquidCrystal.h>

It's always a good idea to start very small, then work up. When you write a big program like this without testing along the way, there is a lot that can go wrong. I recommend stripping down everything to the basics - just try to output Serial messages when joystick events happen. Then, when you get that working, get one of the motors to turn. Then the other. Then the LCD, etc.

Have you done any troubleshooting so far? Do any Serial messages come through? Do some things work, but not others? Does the LCD have anything on it? Does the Arduino IDE compiler output any errors? Part of being an electronics nerd is being able to ask yourself all these questions and find answers, rather than asking other people to fix your work for you. But I've been there, so don't feel too bad.

*hint: The first line of the loop() method is missing parens - instead of "detect;" it should read "detect();". But I'll bet there's more to it than that :wink:
