From the Brainwagon Archive: Silly Arduino Project #1: A Trivial Beacon
One year ago tody, I tinkered together a very simple program and keying circuit to use my Arduino to send out a simple Morse Code beacon message.
It seems like complete overkill to me to use a $30 microcontroller to do this task though. A couple of different groups have created PICs and the like which can be used to do the same, with a total cost of well under $10 (the chips are probably around $2 or so a piece). I keep thinking that what I should do is code up a simple version of this kind of application in ATMEL AVR assembly code and make it available. I can envision a simple web based application that would enable you to enter a list of beacon messages you want, and then hit a button and download the necessary firmware, all assembled and ready to go. Just burn and go…
I need more hours in the day.
