Controlling_Pixel LED_via_Wifi

How to make

Open the code in Arduino IDE
Put your router SSID and Password to following lines. (You can see those lines on top of the Controlling_PixelLED_via_wifi.ino file.)
and put these details as well.
- LED_PIN :- The NodeMCU pin you use to connect pixel LED data wire.
- NUM_LEDS :- Number of LEDs you use.
- LED_TYPE :- LEDs Type (ex :- WS2811, WS2812B ... )
- COLOR_ORDER :- No need to change necessarily.
chnage the gateway ip address. put your router ip address here.
```
IPAddress gateway(192, 168, 8, 1);
```
change the local_IP address if you want.
```
IPAddress local_IP(192, 168, 8, 107);
```
Then upload the code to the NodeMCU board and after uploding done connect to the LEDs.
Connect your device (Smart Phone or PC) which you use to control the NodeMCU to the same router.
Then open a web browser, enter the IP which you above configured as local_ip to URL and press enter.
Then you will be able to control your LEDs.
- Pressing the play button you can see how that particular pattern run.
- Put the tick mark to patterns you like. Then click the upload button. The patterns you ticked. runs one after one repeatedly.

Additional

You can change pattern's name by changing the patternNames array as follow.

String patternNames[] = {
  "Running",
  "Rainbow",
  ...
};

If you don't have a router, you can use mobile hotspot.

You can change the running time of a particular pattern.

There are separate blocks for each pattern in 'void loop' by separating like follow.

//pattern 1  ----------------------------------------------------
  if ((patternCount == 1 && px[0] == 1 && quickPlay == 0 && (millis() - timecount < 60000)) || quickPlay == 1) {
     ..........
     ..........
     ..........
  }

  delay(1);
  if ((patternCount == 1 && quickPlay == 0 && (millis() - timecount > 60000)) || (patternCount == 1 && px[0] == 0)) {
    timecount = millis();
    patternCount = 2;
    Serial.println("Pattern 2");
  }

you can see first and second if condition have '(millis() - timecount < 60000)' and '(millis() - timecount > 60000))'
change that value as you want (in here 60000). same value for both
That value indicates the running time in milliseconds
ex :- If you want to increase the running time, put a larger value.

You can add patterns as you wish.
- Increase numOfPatterns
```
const int numOfPatterns = 9; // number of patterns
```
- Add a pattern name to the patternNames array
```
String patternNames[] = {
"Pattern 1",
"Pattern 2"
....

};
```
- go to the void loop. I added some template pattern blocks by commenting.
- Remove the comments symbols of the first one of those.
```
if ((patternCount == 10 && px[9] == 1 && quickPlay == 0 && (millis() - timecount < 30000)) || quickPlay == 10) {


  }
  if ((patternCount == 10 && quickPlay == 0 && (millis() - timecount > 30000))  || (patternCount == 10 && px[9] == 0)) {
    timecount = millis();
    patternCount = 11;
    Serial.println("Pattern 11");
  }
```
- Write your code within the first if condition. but there are restrictions for that.
  - You shouldn't use 'delay' function or any loop that the execution sequence hold down within that block.
  - It is ok for a maximum delay of 1 second or 2 seconds.
  - The reason for that, if it has a delay. while running that pattern, you would not able to operate the NodeMCU by using webApp.
- patternCount indicates the next pattern number.
- patternCount of the last pattern should be 1.
