Press and hold IR remote control button code

Projects Programming
1

I am working on a robot car project and on lesson 2, i added an IR remote and i was wondering how i could make it so when you press and hold a button, the car will keep moving instead of moving for a little bit then stoping.
Here is the code i have now:

#include <ir_Lego_PF_BitStreamEncoder.h>
#include <boarddefs.h>
#include <IRremoteInt.h>
#include <IRremote.h>

Try commenting this line - IRresults.value = 0;
When you comment it the car will not stop until you press the stop button

Not all IR remote buttons repeat. When they do they will typically send the same code again or a separate code that means 'repeat'. If you want some action to continue "as long as I am pressing the button" you need:

  1. A button on your remote that repeats.
    and
  2. A timer in your receiver to detect when the repeats have stopped.
    Each time a 'repeat' arrives, record the millis() time. When (millis() - recordedTime > TimeBetweenRepeats) you know that whatever was repeating has stopped.

@johnwasser I am using this IR remote with this IR receiver. Do you know if this repeats?

You can easily tell if a button on your remote repeats. Connect your receiver to an LED and see if it blinks once when you hold the button or blinks repeatedly as long as you hold the button.
