I'm attempting to code a step motor with a wireless IR receiver. My codes fine, but I get this error whenever I attempt to upload
Arduino: 1.8.0 (Mac OS X), Board: "Arduino/Genuino Uno"
Sketch uses 4106 bytes (12%) of program storage space. Maximum is 32256 bytes.
Global variables use 257 bytes (12%) of dynamic memory, leaving 1791 bytes for local variables. Maximum is 2048 bytes.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
Here is my code:
#include "Stepper.h"
#include "IRremote.h"
/*----- Variables, Pins -----*/
#define STEPS 32 // Number of steps per revolution of Internal shaft
int Steps2Take; // 2048 = 1 Revolution
int receiver = 6; // Signal Pin of IR receiver to Arduino Digital Pin 6
/*-----( Declare objects )-----*/
// Setup of proper sequencing for Motor Driver Pins
// In1, In2, In3, In4 in the sequence 1-3-2-4
Stepper small_stepper(STEPS, 8, 10, 9, 11);
IRrecv irrecv(receiver); // create instance of 'irrecv'
decode_results results; // create instance of 'decode_results'
void setup()
{
irrecv.enableIRIn(); // Start the receiver
}
void loop()
{
if (irrecv.decode(&results)) // have we received an IR signal?
{
switch(results.value)
{
case 0xFF629D: // UP button pressed
small_stepper.setSpeed(500); //Max seems to be 700
Steps2Take = 2048; // Rotate CW
small_stepper.step(Steps2Take);
delay(2000);
break;
case 0xFFA857: // DOWN button pressed
small_stepper.setSpeed(500);
Steps2Take = -2048; // Rotate CCW
small_stepper.step(Steps2Take);
delay(2000);
break;
}
irrecv.resume(); // receive the next value
}
}/* --end main loop -- */
I've also attached the schematics below
