Persistence of Vision (POV) is made with stripe of LEDs which rotates at 360 degree.
If we assume the stripe is with 100 LEDs you can make square “screen” with size approx 140×140 pixels.
Make code which converts 140×140 pixels picture to array of LED stripe values for each angle 0-360.
When LED from the stripe are not at exact pixel positions the best way to set their value is to mediate the value depend on the closest pixel neighbors.
You can code the solution in any programming language during the weekend and have to submit it to firstname.lastname@example.org latest on Sunday November 24th.
On Monday we will upload the solutions on GitHub https://github.com/OLIMEX/WPC
You can play with your real name or with nick if you want to be anonymous, we will not disclosure your personal info if you do not want to.
