1  Using Arduino / Programming Questions / Re: IR Library Help on: January 20, 2013, 11:02:23 am
Quick5pnt0 : thread hijacking...was sincerely unaware of this, thanks for letting me know.  smiley-red

I'm using the 5940 library in the same sketch but pin 3 is reserved for it, just wanted to use the IR Remote library to produce a 38khz in the same sketch. Upon more research, i'm realizing that using an external 555 timer circuit to produce a 38khz signal for an IR Emitter is likely a better option.

Thanks for replying! smiley

I downloaded Ken Shirriff's IR library,

question:


I simply want to use Pin 5 for the IR emitter on my Arduino Uno.
How do I change and use another PWM output pin other than Pin 3?


Any other PWM pin 5,6,9,10,11 doesn't work either... except pin 3.


Do I have to modify some code in the library file: IRremote.h ? 


#include <IRremote.h>

#define PIN_IR 3   // I want to use Pin 5 or another PWM output
#define PIN_DETECT 2
#define PIN_STATUS 13


IRsend irsend;
void setup()
{
  pinMode(PIN_DETECT, INPUT);
  pinMode(PIN_STATUS, OUTPUT);
  irsend.enableIROut(38);
  irsend.mark(0);
}

void loop() {
  digitalWrite(PIN_STATUS, !digitalRead(PIN_DETECT));
}





Any ideas?

@CrossRoads:

yes. I want to multiplex and take advantage of the 3 TLC5940's at my disposal, would prefer to use it with its 16 outputs rather than the 74HC595.

But now… distracted by the ShiftPWM library.

Hmmm....

I too am seeking to graduate from controlling several single color LED's to controlling
more than 16 RGB LED's using TLC5940's. But i'm now realizing, the 74HC595 appears to be an interesting choice as well.

Thanks all!

many options, more studying to do.

Thank you Crossroads,

this voltage consumption topic is great!

Much appreciated!

Hi all,

I have a project that i've completed with the Arduino Uno R3.
I want to purchase and use the Arduino Micro due to its smaller footprint. I've read your comments on the Arduino Mini and Pro Mini regarding their power requirements.

Does the Arduino Micro require a separate 5V regulator for its power source?
Does it have a built in regulator?

And...with the exception of a few more analog and digital I/O pins on the Arduino Micro,
can I expect the exact same functionality as I currently have with the Arduino Uno R3?

Any details will help,

Thanks!
