Infrared (IR) remote control

Hi all
I am trying to control a stepper motor using an IR remote control the problem is when any button is pressed the HEX code produced is only momentary, it is repetitive though.

The sketch I have cobbled together from other peoples work is a bit clunky and will not latch the motor on, as by the time it has started to move, the HEX code has gone and the motor stops.

Is there a way to latch the motor on while it is receiving the correct HEX code?

I have pasted the code below and would appreciate any help.

Many Thanks

#include <IRremote.h>

const int RECV_PIN = 9; // the pin where you connect the output pin of the IR receiver
const byte Step = 2;    // one step per change
const byte Dir = 3;     // the direction
const byte Enable = 4;  // turn EasyDriver off when not turning
const byte MS1 = 7;     // 1/4 the stepping rate 1
const byte MS2 = 8;     // 1/8 the stepping rate 2
const byte ledPin = 13;    // led plugged to digital pin 13
const byte button_slow = 6;    // button plugged to digital pin 5
const byte button_fast = 5;   // button plugged to digital pin 6

bool blinking_1 = false;  //defines when blinking should occur
bool blinking_2 = false;  //defines when blinking should occur
unsigned long blinkInterval_1 = 10;  // number of milliseconds for blink
unsigned long currentMillis_1; // variables to track millis()
unsigned long previousMillis_1;

unsigned long blinkInterval_2 = 50;  // number of milliseconds for blink
unsigned long currentMillis_2; // variables to track millis()
unsigned long previousMillis_2;

// variables will change:
int buttonState = 0;         // current state of the button
int lastButtonState = 0;     // previous state of the button
int LEDstate = 0;        // “0” is off, “1” is on.

IRrecv irrecv(RECV_PIN);

Welcome to the Forum. You have posted code without using code tags. The code tags make the code look

like this

when posting source code files. It makes it easier to read, and can be copied with a single mouse click. Also, if you don’t do it, some of the character sequences in the code can be misinterpred by the forum code as italics or funny emoticons.
If you have already posted without using code tags, open your message and select “modify” from the pull down menu labelled, “More”, at the lower left corner of the message. Highlight your code by selecting it (it turns blue), and then click on the “</>” icon at the upper left hand corner. Click on the “Save” button. Code tags can also be inserted manually in the forum text using the code and /code metatags.

Please read these two posts:

Read this before posting a programming question …

Many questions can be answered by reading the documentation which is provided with the IDE, available under the help tab, or online here.

There are many other things that programmers do to make their code understandable. Please do them, as a courtesy to the members who volunteer their time to help you here. One is to use a standard indentation to clearly show the code blocks. Never put more than one statement per line. Place any brackets by themselves on a separate line. Before posting the code, use Ctrl-T in the IDE to reformat the code in a standard format, which makes it easier for us to read.

Interesting concept. Maybe it is the relationship between parents and their teenage children ? :)
