Announcing a competition- Cash prize, at least $40, could be as much as $60. "Second prizes" possible too.
ANYWAY... the prize will go to the best example of a Morse code reading ATTiny. (There's a parallel competion, with top prize $30 for similar, but done in ordinary Arduino.)
Details... and some help with the programming... at...
I hope you'll find it fun? And maybe pass on news of the competition to other forums, etc?
The reader should calibrate dot and dash lengths during the attention A's at the start of the message and the sender should keep to those. An AVR can poll the line digitally over 50 times a millisecond, we detect bounce.. morse code is not a big deal.
Do I want to enter a contest where all entries become property of someone else for chicken feed? I don't think so, at least when I give code away I can't be stopped from using it!

Who said anything about stopping you using it??
The As idea is good... would certainly increase an entry's chance of winning. But is not a requirement for a valid entry.
