Arduino fire pager

[Dispatrick]

Looking to create an arduino fire pager. Basically the scanner would be hooked up from the headphone jack into the arduino jack. it would simply just be listening for the specific tone sequence. When the arduino recognizes the tones in hz it would flash the LED's on the board and make the beeper on beep on the board.

Anyone have any experience with a project like this or know of any resources?

thank you!!

I have arduino experience. you didnt explicitly say this but i expect you want to show the page messages too ? so you would need a sound board addon likely, and then hopefully be able to find a pager library you could port over, (i doubt on exists but you should search). i think it might be easier and better just to make one with pi zero $5 board. it has likely all you need.
I was thinking about something similar to make a 'plug & play' P25 decoder for standard scanners/boafengs, just plug it into headphone jack and it plays decoded audio of tuned channel.

Not sure what your end goal is. We did something similar with a Raspberry Pi, but used an e-mail notification from CAD to trigger bells, lights, etc. But if you have the same tones every time, wouldn't the project be simplified by getting a Minitor or Unication pager with the respective manufacturer's amplified charger, and use the contact closure as an input on the Arduino to trigger the output? I guess you are trying to have different tones do different things?

an arduino has a microcontroller, a raspi (or similar) has a microprocessor. I feel you will burn up LOTS of arduino cycles trying to process realtime audio from a source, and then trying to make it act on something. It might be the wrong hardware solution here. A raspi would be able to call upon any library you need to get what ever you want done.

You wouldn't even need a scanner for the audio source if you used something like a pi zero, the hardest part would be soldering the 4 wires on to it (or using a breakout board) for a USB-A port for the SDR dongle to plug into.

There is a version of Two-Tone Decode that is specifically for the RaspberryPI, which would do a better job. (Unless you are looking to use this as a wearable item.)

What are you planning to use to receive the radio signal?

 

[Dispatrick]

Thank you for all the responses! I plan on using a scanner to receive the signal. it'll just be from the headphone jack of the scanner into the audio input jack on the unit. Not a wearable item. Just a project to help improve my understanding of Arudino and similar systems.

i would not recommend this as a easy project to get into arduino with....
