Another Nishijin UFO - "Number 2"

[CarlW]

This vintage Nishijin UFO had a bad circuit board.

This project replaced the wheat bulbs with LEDs, energized the OEM solenoid with a MOS FET,
replaced the circuit board with an Arduino UNO R3 and an Adafruit shield.

The second time is easier!

Special thanks to Magic Dan and Baseballguy247.

NARRATIVE
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
Topper animation 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
Topper animation 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
Topper animation 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
Topper animation 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
Topper animation on
ANY Switch
UFO closes (solenoid no power)
All lights off
Topper animation OFF

Dec 2021 Notes:
LEDs 1 through 4 are white, 5 through 12 are green
LEDs 11 & 12 are for second UFO switch
Topper added for two 8x8 matrixes

Topper Notes
The Topper code starts with Case 1 and ends after Case 5
A lot of this code is copied from Adafruit examples.

Compiled including Topper Code
Sketch uses 8672 bytes (26%) of program storage space. Maximum is 32256 bytes.
Global variables use 281 bytes (13%) of dynamic memory, leaving 1767 bytes for local variables.
Maximum is 2048 bytes.
