i'm thinking of using an arduino uno to create a POV led display. does anyone know any tutorials online? (i have googled it, just wondering if you will know of a specific one) if not what are the basics needed to create one? whats the best type of motor would you need, would a simple dc motor do?
There is a 'slight' amount of tinkering around needed. Once you have your LEDs wired and your 'position start' sensor sorted and you know what you want to display, you're essentially there.
(Once I've sobered up, I'll say more).
Timing to put it simply. Once the 'start' signal has occured you need to adjust the on and off times of your LEDs to create the display. This all depends on the complexity of your desired display. Say for example the start signal is in the 6 O'clock position, and you want your message to start in the 9 O'clock position. You need a delay. Then you need a delay for the LEDs to be on / off (more delays). You need also to take into consideration the speed of the motor, so you can display all you want, where you want before you get the next start signal.
