ATTiny85 universal remote sending random signals

darthmater · July 23, 2024, 7:27pm

I've been following instructions on how to make a universal remote from an ATTiny85 microcontroller using this video: https://www.youtube.com/watch?v=_nm4if-lusI&list=WL&index=4

From there I used the IRremote library (4.1.0 version) to work with this code shown here:

#include <IRremote.h>

const byte butonPin = 2; //button input
const byte IRPin = 1; // LED output

void setup()
{
   // connect button to ground and input
   pinMode(butonPin, INPUT_PULLUP);

   IrSender.begin(IRPin);
}

void loop()
{
   static bool lastButtonState = HIGH;
   bool buttonState = digitalRead(butonPin);
   if (buttonState != lastButtonState)
   {
      if (digitalRead(butonPin) == HIGH) {
      
      IrSender.sendNEC(0xEB14FD02, 32);
      }
      lastButtonState = buttonState;
   }
}

I asked the ATTiny to send this signal (0xEB14FD02) using the remote circuit shown in the YouTube video and tried to see if my arduino could pick it up on the serial monitor using the ReceiveDump example included in the library.

Here is the response from the old remote that I copied the signal from:

I am positive the circuit is setup properly but I am unsure if my coding was done correctly. If anyone has any guidance they can provide as to why my ATTiny is sending random signals rather than what it was programed to send, I would be most grateful.

Thank you for your time

mrpotatodude · July 23, 2024, 8:36pm

I think you need to use an example for the newer version of the library. sendNEC() takes 3 arguments: address, command and repeats. Maybe try IrSender.sendNEC(0x2, 0x14, 0);.
Did this fix it?

The ATTiny is still just sending one random signal after another.

Can you please try to put a delay(200) into your loop-function? I've tried it with an Arduino UNO and a logic analyzer. Seems to be working fine. Your button isn't debounced so it could cause the send-function to run again. I'm not completely sure, if this could cause trouble but there is another thread where this was also suggested: IR send not sending consistent signal

darthmater · July 29, 2024, 9:51pm

Not exactly sure I did if i did it right but i added the delay as such:

#include <IRremote.h>

const byte butonPin = 2; //button input
const byte IRPin = 1; // LED output

void setup()
{delay(200);
{
// connect button to ground and input
pinMode(butonPin, INPUT_PULLUP);

IrSender.begin(IRPin);
}
}
void loop()

{
static bool lastButtonState = HIGH;
bool buttonState = digitalRead(butonPin);
if (buttonState != lastButtonState)
{
if (digitalRead(butonPin) == HIGH) {

  IrSender.sendNEC(0xEB14FD02, 32);
  }
  lastButtonState = buttonState;

}
}

Still popping off random signals on the receiving end so it dosen't look like thar fixed it. I appreciate the help though so please let me know if you have any other ideas.

mrpotatodude · July 29, 2024, 10:15pm

You did put the delay() into setup(). Try it like the following example:

#include <IRremote.h>

const byte IRPin = 1; // LED output

void setup()
{
   IrSender.begin(IRPin);
}

void loop()
{
    delay(200);
    IrSender.sendNEC(0xEB14FD02, 32);
}

You can of course modify it to work when using the button. I just used it as test code.

Looks like wrong clock settings. Test with a 1 second blink.
