A small hand hold unit allows you to write a message in the air just by waving. It uses an Arduino NanoV3 to create the message in a simple straightforward way.
Write the message in Excel and define HIGH or LOW per led in the sketch. An example sketch is attached, the heart may need some surgery :-). The message writes continuously.
If a reed relay replaces the fixed connection and the program is adapted, the text can start at a defined spot, where the relay is activated by a small neodymium magnet.
A 9 volt block cell provides the power.
