This is a preliminary project to the bicycle wheel POV (persistence of vision) project I want to tackle. I’ve attached my sketch and a photo of my prototype board to give you an idea of how to try this yourself.
I was surprised how difficult it was to achieve the desired affect by just waving the board back and forth. I’ve seen commercial products such as http://www.instructables.com/id/Magic-POV-Wand-yet-another-POV-toy/ so didn’t expect it to be so difficult. With some practice and by squinting my eyes I was able to see some characters. You can see from the code I attempted the penultimate “Hello World” but it seems the longer the message the more difficult it was to see. Play around with the column delay until you find a usable value.
If you found this fun or interesting please make a small donation to my PayPal account at https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=GTBD7T7BXPGQY. I have many more Arduino projects in mind and appreciate your support.
