Hi
I am sending IR signal using Arduino UNO board. The problem I am having is it is transmitting for indefinite period. Can anyone help me how can I fix this problem.
My Arduino code:
int IRledPin = 13; // LED connected to digital pin 13
void setup() {
void loop()
void pulseIR(long microsecs) {
cli(); // this turns off any background interrupts
while (microsecs > 0) {
// so 26 microseconds altogether
sei(); // this turns them back on
void SendchannelA() {
pulseIR(1553);
}
The problem I am having is it is transmitting for indefinite period.
You've told it to? This loop infinitely cycles and pulses your IR pins.
void loop()
{
Serial.println("Sending IR signal");
SendchannelA();
delay(1000);
}

Sorry. I aplogise. Here is my code.
int IRledPin = 13; // LED connected to digital pin 13
void setup() {
// initialize the IR digital pin as an output:
pinMode(IRledPin, OUTPUT);
Serial.begin(9600);
}
void loop()
{
Serial.println("Sending IR signal");
SendchannelA();
delay(1000);
}
void pulseIR(long microsecs) {
cli(); // this turns off any background interrupts
while (microsecs > 0) {
// 38 kHz is about 13 microseconds high and 13 microseconds low
digitalWrite(IRledPin, HIGH);
delayMicroseconds(8);
digitalWrite(IRledPin, LOW);
delayMicroseconds(8);
// so 26 microseconds altogether
microsecs -= 26;
}
sei(); // this turns them back on
}
void SendchannelA() {
pulseIR(1553);
