Can UNO handle my project? PIR, MOtor, RGB LED's ,FOG Machines,

I Tried before last Halloween to make this Prop Controller.

Taking the idea from Dead with Dave controller he made. Halloween Yard Haunt Controller Pandemic Cemetery

To give you idea it would be a Prop of Maleficent that would come to life with a person sets off the PIR then using a MP3 board and SD board attached to the Arduino a motor would turn on make her stuff spin around. With a clear ball on top of the stuff. With RGB leds in it to change colors. Also having lights around the yard RGB LED strips that would change and mach the stuff color. Turning on two for machines also. I new to programming. I know this is way hard for someone so new. But can one board handle all this. I using a UNO should I get a different board? I wrote the code. Then end up hiring someone to rewrite it for me. Because I could get a lot of stuff to work. Let me know if anyone could give me any help on this idea project. Even would pay someone for their help.

Maybe this thread belongs in the gigs forum?

I would think that the Uno would be sufficient for the project you describe.

UNO seems more than adequate for what you are doing.

Your code does have a few problems:

The comparison of the input port is incorrect:

 if (digitalRead(pirSensor==HIGH)) // this compares the value of pirSensor to HIGH, then reads either port 1 (if true) or 0 (if false)

if (digitalRead(pirSensor) == HIGH) //should be written like this

You have the comparisons for the millis() timing correct, but after each of the intervals has been reached you are resetting previousMillis. The timers are all based on cumulative time since the PIR sensor triggered the sequence, so previousMillis needs to remain the same until all the timing events have completed. The way the code is written, you get to the 9 second event, then reset the timer, which causes the code to keep repeating the event at 9 seconds forever and never get beyond that point. If you simply remove the reset of previousMillis, then you will run into the problem that once you reach each timing interval, then each time through loop the test for the time interval will be true and the code will be executed repeated.

This is a classic example of what a State Machine is used for, so you might want to do some research on that topic.
