A model slot machine simulates the real thing by flickering 3 led’s in the three windows. The various fruits in the windows are depicted by different brightnesses of the LED. The blur of the fast spinning wheels is accomplished with Fade statements.
This is a playable random machine where each wheel has a chance of stopping on different fruits. When all three wheels have stopped, the result is the brightness of each fruit.
If LED’s face forward through the windows, they may be quite bright. Use Theme Designer to turn them down significantly.
There are two versions, identical except for the brightness of the fruits. The playable version has easily discernible fruits, so you can see if you won. The visual version has softer contrast, which might look more realistic in a model.
The file is too large to list here. We included the opening lines showing where the two versions are selected. Comment out one version or the other. The full length is attached.
