Nishijin Vintage UFO

[CarlW]

Project is to replace broken, obsolete circuit board with Arduino.

Special thanks to Magic Dan!

UFO component labels.jpg

Components:
Light 1 through Light 12 (11 & 12 are additional)

START Switch (Center)

"NOT" START Switches:
Center Switch
Top Left Switch
Bottom Left Switch
Top Right Switch
Bottom Right Switch
OEM 24V Solenoid controlled by new MOS FET

Sequence:
Start up light check
Before start, open and close UFO, light each LED

Start:
UFO Closed
Ball in any "NOT" START Switch
Nothing happens

Ball in top center (START Switch) - FIRST PAYOUT
UFO opens (solenoid powered)
Center bottom lights blink together @ 1/2 second (Light 7 & Light 8)
Light 1 on

Until UFO closes:
ANY Switch (START or NOT START) - SECOND PAYOUT
UFO remains open (solenoid powered via MOS FET)
Center bottom lights blink together @ 1/2 second (Light 7 & Light 8)
Light 1 off
Light 2 on
ANY Switch - THIRD PAYOUT
UFO remains open (solenoid powered)
Center bottom lights blink together @ 1/2 second (Light 7 & Light 8)
Light 2 off
Light 3 on
ANY Switch - FOURTH PAYOUT
UFO remains open (solenoid powered)
Center bottom lights blink together @ 1/2 second (Light 7 & Light 8)
Light 3 off
Light 4 on
ANY Switch - FIFTH PAYOUT
UFO remains open (solenoid powered)
Light 4 on
Center bottom lights remain blink together faster @ 1/4 second (Light 7 & Light 8) alternating with Center top lights (Light 5 & Light 6)
Light 9 and Light 10 on
Light 11 and Light 12 on
ANY Switch
UFO closes (solenoid no power)
All lights off

Nov 2021 Notes:
LEDs 1 through 4 are white, 5 through 12 are green
LEDs 11 & 12 are for second UFO switch

Cool project.

Isn't a mega a bit of an overkill. wouldn't a nano or uno be a lot smaller
Mind you with that many outputs. might make it easier than having to start stuffing shift registers in .

That is a great point!

Had MEGAs available is real answer...

Uses 15 pins.

Sketch uses 3118 bytes (1%) of program storage space. Maximum is 253952 bytes.
Global variables use 31 bytes (0%) of dynamic memory, leaving 8161 bytes for local variables. Maximum is 8192 bytes.

Yep, overkill...
