its been a while since I posted this link:
almost ten years in fact,
back then I wanted to send morse via some PMR radios, and have it recieved and decoded back into text.
I succeeded in my needs on that project as all I wanted to do was to send a reconizable code upon an event being monitored by the arduino, as a crude alarm system.
I was able to get a few of the letters of the alphabet to repeatably send. I called it good and kept on with the project.
10 years later and I still have the itch that needs scratching. I still want to be able to send data over a radio link with an arduino.
does anyone know of a better way of doing it these days ?
The criteria I imagine that I want are the following:
- have a text input on a pc and or keypad/lcd combo.
- have the text sent over PMR radios or similar, the key being freely availble radios, and cheaply available.
- have it decoded at the other end, and displayed on the lcd and or pc in a serial output etc.
since trying years ago ive got certain radio modules to work, modules made for the job etc, but I still want to try and use arduino.
any help would be appreciated as I delve into google and try to find a newer solution .
