IR remote

Using Arduino Project Guidance
#1

Hello everyone:)

Iam trying to built a remote controller based on voice recognition for a school project. I got the voice recognition part to work but having some problem with sending IR.

Iam using ken shirriff library for receving and sending, i got a RC6 remote controll at home but dont really understand how it works.
I got the receving part to work and have already got the codes for all the buttons but having issues for sending.

Decoded RC6 1000C (20 bits) // powerOn
Decoded RC6 10001 (20 bits) // channel one

Let’s say i want to change to channel one from the arduino

#include <IRremote.h>

IRsend irsend;

void setup()
{
Serial.begin(9600);
}

void loop() {
if (Serial.read() != -1) {
irsend.sendSony(0x8100, 20); // i got the 10001 from channel1 and it’s 20 bits, is this right?
delay(100);
}
}
}

i got a ir led connceted on pin 3 with a 100ohm to GND

How did you arrive at the value 10001 for channel 1? I think you should post the code that printed that value.

Mixing decimal, binary, and hexadecimal values is a recipe for disaster.

The value that i got was like this:
Decoded RC6 10001 (20 bits)
raw code:(42){-11640,2750,900,400,900,500,400,450,400,450,900,950,350,500,400,450,450,450,400,450,450,450,450,450,400,450,450,500,400,450,400,500,400,450,450,450,400,500,400,450,400,950}
