POV Globe Using Arduino
If you like LED display project here is another cool project : Arduino based POV globe. This persistence of vision project able to displaying monocolour bitmaps up to 72 pixels high and x width. (uses 72 LEDs, and one input to get rotation speed). The main component in this project is atmega328P, 72 SMD LED, Reed switch (sensor) and power supply.
Arduino byte array for images are generated using the c# program. Image displayed is synch’d to speed of motor using a reed switch, this allows image to display around hole globe correctly, and maintain a constant position. To work well you have to ensure that the reed switch is close to the magnet.
