Remember that the goal is to be able to display whatever image only by rotating the strip. Therefore it is a natural step to convert the image to a polar representation. For this, an external script was written in Python, since its Image library is very handy to work with. Unfortunately, this library is only supported in Python 2.
POV Display using Arduino - DiY Propeller (Rotating LED) Display
Persistence of Vision, or POV, occurs when a visual image seems to persist continuously when a stream of light is repeatedly interrupted for very brief instances and does not enter our eyes during those durations. The human eye cannot process more than images per second. When a series of images more is presented in quick succession, it gives us the illusion that the images are in motion. This is the basic principle behind the making of the animated movies. Once done, fix the LEDs to it. We are going to use 8 red LEDs. To protect the LEDs from blowing up due to high voltage supply 5V we are going to use resistors.
Now, let me take you through a step-by-step construction of the POV Display. In order to fix the motor to the board, I have used a pair of rubber holders on either side of the board. Position these headers with the hole for motor as center. Solder them to the perf board.
