OK, I've been reading post from here and Reddit and have kind of stuck in a ditch. I'm trying to Connect Arduino to the IR receiver input. I've printed out this post Bypassing IR control on HDMI switcher - Project Guidance - Arduino Forum and read it over and over and cant figure out where the Hex code is suppose to go.
Me2. I can read your contribution over and over again and cannot find out what you want to accomplish 
Please elaborate what you have and what you want. Did you run the IRremote examples?
Yes i did run "IRsendRawDemo, IRsendDemo, and IRrecvDump". But the code i need to figure out is what "wystem" (from the Forum in the link i listed above) some how he got it to work. Since he is a Guest and the posts are almost 5 years ago i can't inbox him for questions. I'm attaching the *.ino. I'm just needing help understanding where the decoded NEC HEX code from the Remote would go inside this program to be sent to the receiver Hard Wired. No IR-LED nor IR Receiver.

Please include your sketch in Code Tags </>, see sticky topics on top of the forum.
Why don't you use Serial for wire transmission?
Which RGB controller, what kind of input does it expect?
// pulse parameters in usec
#define HDR_MARK 9000
#define HDR_SPACE 4500
#define BIT_MARK 560
#define ONE_SPACE 1690
#define ZERO_SPACE 560
#define TOPBIT 0x80000000
const int OutputPin = 11;
void send() {
Serial.println("Sending");
mark(HDR_MARK);
space(HDR_SPACE);
for (int i = 0; i < 7; i++) {
mark(BIT_MARK);
space(ZERO_SPACE);
}
for (int i = 0; i < 8; i++) {
mark(BIT_MARK);
space(ONE_SPACE);
}
for (int i = 0; i < 1; i++) {
mark(BIT_MARK);
space(ZERO_SPACE);
}
for (int i = 0; i < 5; i++) {
mark(BIT_MARK);
space(ONE_SPACE);
}
for (int i = 0; i < 8; i++) {
mark(BIT_MARK);
space(ZERO_SPACE);
}
for (int i = 0; i < 3; i++) {
mark(BIT_MARK);
space(ONE_SPACE);
}
mark(BIT_MARK);
space(0);
}
void mark(int time) {
digitalWrite(OutputPin, LOW);
delayMicroseconds(time);
}
void space(int time) {
digitalWrite(OutputPin, HIGH);
delayMicroseconds(time);
}
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
pinMode(OutputPin, OUTPUT);
digitalWrite(OutputPin, HIGH);
}
void loop() {
// put your main code here, to run repeatedly:
if (Serial.available() > 0) {
char inChar = Serial.read();
if(inChar == '!' ){
//digitalWrite(OutputPin, HIGH);
send();
//digitalWrite(OutputPin, LOW);
}
}
}
No idea if Serial would work, honestly im still a new. i keep learning new stuff for Arduino everyday and still haven't mastered any of this. i figured serial was a 2-way communication data type and the receiver only has an input.
The controller is a cheap ($5) RGB strip controller from Monster i bought from walmart. I was hoping to use this instead of making my own controller because its so small and pre-made.
Please understand that "a controller from walmart" is not really helpful. Please supply a link to the data sheet, where the communication protocol is described.
Where I live we don't even have Walmarts (or even $) so a description like "a cheap ($5) RGB strip controller from Monster i bought from walmart" isn't lightening my ignorance one little bit.
We really need a datasheet but even a picture and any operating instructions you have might help a bit.
