Motion Sensor LED Strip with Reset Button

Projects General Guidance
1

Hello, I have made a program and setup that has a motion sensor and a LED light strip. When the motion sensor is triggered it turns on the LED strip to whatever Animation i set it to. I am trying to implement a button that you can press that turns off the animation and resets everything so i can trip the motion sensor again. The Program is attached i will also put the segment that controls the motion sensor below.

void loop() {



 senseMotion = digitalRead(PIR);

 if (senseMotion == HIGH) {    // Tells lights to turn on
   scanner(127,0,127, 15); //Tells what animation for the lights to play
   strip.show(); // Initialize all pixels to 'off'
   delay(100);

 } else {
       val = digitalRead(ButtonPIN);
       if (val == HIGH) {
         strip.Color(0,0,0);
         strip.show();
        
       }


 }
}

Is that all the code?
Please post it all.

Here is all the code.

#include <Adafruit_NeoPixel.h>

// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
//   NEO_RGB     Pixels are wired for RGB bitstream
//   NEO_GRB     Pixels are wired for GRB bitstream
//   NEO_KHZ400  400 KHz bitstream (e.g. FLORA pixels)
//   NEO_KHZ800  800 KHz bitstream (e.g. High Density LED strip)

Adafruit_NeoPixel strip = Adafruit_NeoPixel(20, 6, NEO_GRB + NEO_KHZ800);

const byte PIR = 2;   // motion detector input pin
byte senseMotion = 0; // variable to hold current state of motion detector

@Beamer25, do not cross-post. Other thread removed.

You need to implement the anamation was a state machine.
That means moving all the delays and replacing the for loop with a one shot code. That is code that does one iteration and then returns. I have posted my example of this dozens of times lately.

Do not cross post. I have reported your other post, it will probably be deleted.
Do read the how to use this forum sticky post for the rules here.
Cross posting make people cross.

Thank you I will try that and very sorry, new to the forms.

Thanks,

I put the code I had in the loop into a void setup and i tried to compile it and it gave me

C:\Users\COLTON~1\AppData\Local\Temp\ccgtTII3.ltrans0.ltrans.o: In function `main':

You have not got a loop function defined. You need to have a loop function when programming on the Arduino.

You had one before why have you removed it?
