(Persistence of Vision) POV as you type (a typewriter way to write on a POV unit in real time). A real time way to send characters and write on a Persistence of Vision unit.
Type in a computer keyboard, and send the characters via RF 433 Mhz to the POV unit, in real time.
I used a Hall Effect Sensor for stabilization as well creating a starting point for the writing position.
The material list is here:
** Parts for the Transmitter: RF Transmitter 433 Mhz Arduino Nano USB Cable Notebook or PC RealTerm software
** Parts for the POV rig: Arduino Pro mini 3.7 battery lipo 500 mAh RF 433 Mhz Receiver Mini power Switch Hall Effect Sensor Neodymium Magnets 8 ~ 16 Blue LEDs 220 Ohms Resistor Trimpot 10k Wires 2 x PCB ( one for the horizontal base , and another one for the vertical LEDs) Motor (computer DC fan)
