How to use this app
Send: write some text in the upper box and press "Send", the iPhone 4 and 4S flash will blink long and short according to Morse Code translation you can see in the "Morse code translation" box. You can set the speed of sending with the slider.
Receive: tap "Receive" button long for dash and short for dot. Leave a little time between letters (3 time the dot duration) and longer time for word separation (6 time the dot duration). At the end of the message tap "end".
Learn: write something in "Phrase to send", tap "Send". Observing flash and the "Morse code translation" you can imitate the sequence of dashes and dots with "Receive" button.

Continued use of the flash may dramatically decrease battery life.
