Elro AB440R - HX2262 chip

I recently buy this rc switch set.
I’m trying to replace the remote following this instructions.

Here is the code I currently use :

#include <RCSwitch.h>

RCSwitch mySwitch = RCSwitch(); 

void setup() {
  mySwitch.enableTransmit(11);  
  pinMode(2, OUTPUT);
}

void loop() {
  mySwitch.switchOn("11111", "10000"); // first try for A
  digitalWrite(2, HIGH);
  delay(2000);
  
  // Switch off
  mySwitch.switchOff("11111", "10000");
  digitalWrite(2, LOW);
  delay(2000);
}

I define the code to use following this instructions.

I connect pin 11 of my arduino to the Dout on the remote = Dropbox - 20130913_181534.jpg - Simplify your life

But I can’t get it work, any suggestion ?

I didn't use any welding for my tests. May be it was related to my problem.

2 suggestions:

1st: Put questions like these in Device Hacking.

2nd: Most of these kind of questions, people just connected one wire to the device. But you need a reference, and that is the GND level. So, did you connect the GND of the device (pin 9, labeled VSS here) to the GND pin of your Arduino ?

That is why i put a remark about this in my signoff.

Be sure to have good connections, soldering would be a good and relative permanent connection, if you do the job well.

I'll do this next time, sorry.

I can get it work with a transmitter connected on my breadboard. I only try with on wire on the devise, I'll retry it when I get a soldering iron.

Thank for your advices :)

Hi,

Are there any news on the topic ? I have the same problem and can get force this chip to work with Arduino :/ My topic in Device Hacking:
