hi i am completely new to arduino and its programming had seen a diy project and being impressed purchased all the goods (which has costed me) and now when i am uploading the code it is showing error please someone guide me as to what has to be done or how do i make the script so that i cannot upload without errors
please help
the code is
#include <SoftwareSerial.h>
#include "Arduino.h"
#include <Wire.h>//Include libraries: SoftwareSerial & Wire
SoftwareSerial ESP_BT(0,1); //Define PIN11 & PIN12 as RX and TX pins
#include <Adafruit_GFX.h>
#include <Adafruit_NeoMatrix.h>
#include <Adafruit_NeoPixel.h>
#include <EEPROM.h>
#ifndef PSTR
#define PSTR // Make Arduino Due happy
#endif
#define PIN 5
// MATRIX DECLARATION:
// Parameter 1 = width of NeoPixel matrix
// Parameter 2 = height of matrix
// Parameter 3 = pin number (most are valid)
// Parameter 4 = matrix layout flags, add together as needed:
// NEO_MATRIX_TOP, NEO_MATRIX_BOTTOM, NEO_MATRIX_LEFT, NEO_MATRIX_RIGHT:
// Position of the FIRST LED in the matrix; pick two, e.g.
// NEO_MATRIX_TOP + NEO_MATRIX_LEFT for the top-left corner.
// NEO_MATRIX_ROWS, NEO_MATRIX_COLUMNS: LEDs are arranged in horizontal
// rows or in vertical columns, respectively; pick one or the other.
// NEO_MATRIX_PROGRESSIVE, NEO_MATRIX_ZIGZAG: all rows/columns proceed
// in the same order, or alternate lines reverse direction; pick one.
// See example below for these values in action.
// Parameter 5 = pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_GRBW Pixels are wired for GRBW bitstream (RGB+W NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
// Example for NeoPixel Shield. In this application we'd like to use it
// as a 5x8 tall matrix, with the USB port positioned at the top of the
// Arduino. When held that way, the first pixel is at the top right, and
// lines are arranged in columns, progressive order. The shield uses
// 800 KHz (v2) pixels that expect GRB color data.
