My project is control IR helicopter by arduino, i got the protocal from helicopter's controller (HERE : h
ttp://www.instructables.com/id/The-Easiest-Way-to-Use-Any-IR-Remote-with-Ardiuno/?ALLSTEPS
)
I dont know how to send the bit to helicopter because of some causes such as wait time, time led high or low. please help me and thank you very much.
Do you mean, from your post, that you already know exactly what to send to the Helicopter?
If so please give us an example so we can all be on the same page.
I think the most practial way to make progress is for you to make your best attempt at a sketch and then post it here with an explanation of its shortcomings (if any).
How do you propose to debug your code? (Something that needs to be planned in from the start - especially with anything complex.)
By the way, have you got the original IR controller for the helicopter and does it work?

Thank you,this is my code, i transmit 32 bits but it didn't work, my helicopter same SM s107.

// initialize the IR digital pin as an output:
pinMode(IRledPin, OUTPUT);

Serial.begin(9600);
for (int i=0; i < 13; i++)
pulseValues[i] = 0;

cli(); // this turns off any background interrupts
while (microsecs > 0) {
// 38 kHz is about 13 microseconds high and 13 microseconds low
digitalWrite(IRledPin, HIGH); // this takes about 3 microseconds to happen
delayMicroseconds(10); // hang out for 10 microseconds
digitalWrite(IRledPin, LOW); // this also takes about 3 microseconds
delayMicroseconds(10); // hang out for 10 microseconds
// so 26 microseconds altogether
microsecs -= 26;

I asked 5 questions and you only answered part of one of them. When you answer all the questions I will think about your problem some more. I can't read your mind.
