    Thank you so much for your neat little page on LED effects! I might as well tell you my main goal on here. I would like to program the arduino to rotate a little servo motor that will be connected to a “disco ball” of LED’s. I would like different effects to be called each time I turn on the arduino. (I will be attaching it to a 9V battery with a switch.) I have tried to use random numbers to call your functions, but I cannot get it to work. I have included the LED effects attachment as well as the servo attachment. I would like to know how I call a random function but also call the servo function no matter which LED function gets chosen.



    Ok, I’ve got it.

    Turns out I shouldn’t code at 4 in the morning after a long hard day. I’ve come up with this code. The servo function is hard coded, but there’s no shame in writing a function that works!



    Haha, coding at that time of day can have it’s consequences hahah 

    Sorry for the late reply though – I am in the middle of moving from Europe to the US, and it’s been quite busy, not to mention: all my stuff is in a huge container somewhere on the ocean haha.

    Glad you figured it out though – and thanks for sharing the code.
