Slot Machine with arduino Mega

Hi,
I am a newbie to Arduino and electronics, but I have some knowledge of visual basic and c programming. What I wish to do is make a japanese slot machine with skill stop function.

I am thinking of using:

  • 1 x Arduino Mega 2560
  • 3 x Bi directional stepper motor 12V, 0,33A for the slot machine wheels
  • 3 x SN754410ne H-Bridge
  • 1 x On/Off switch for powering the slot machine On/Off
  • 1 x On/Off switch for digital input for coin input
  • 1 x Button for "Start Spinning".
  • 3 x Buttons for "Stop Wheel 1, 2, 3"
  • 1 x DC power supply
  • Some hookup wire and some breadboard for prototyping

Since I am quite new to electronics I need some pointers on how and if it is possible to make a slot machine with the list of components I have specified, do I need some transistors, diode or resistors as well for the interfacing of the stepper motors etc.?

I am thinking of using a unidirectional stepper motor for the coin payout mechanism, is this a good idea or do someone have a better solution for the coin payout solutions?

Is it possible to compare the 3 wheels (stepper motors) using only software or do I need to have proximity switches to check the 3 wheels for jackpot/payout?

Please help.

Not many answers, huh? Your post sounds too much like "somebody please design my project for me".

OK just a little help, proportional to how clear and specific the question.

YES. Read the tutorials.

First design a mechanism and it will be clear what kind of actuator it needs.

Software alone can keep track of wheel MOVES so long as you know where the stepper motor STARTED (and nothing hangs up or overpowers the motor). You might use a sensor to "find" an index on the wheel after power up, then use software afterwards. Verify the sensor whenever a wheel passes the index position, to make sure nothing got jammed or out of step.
