Arduino Pov " PERSISTENCE of VISION

thingiverse

I stimulate DIY enthusiasts. How I Designed This Point of View I started with this link: http://www.instructables.com/id/Drive-a-Stepper-Motor-with-an-Arduino-and-a-A4988-/. With this link, I set up the stepper driver. This link, http://howtomechatronics.com/tutorials/arduino/how-to-control-stepper-motor-with-a4988-driver-and-arduino/, is where I learned about speed control. I considered using 13 LEDs, but I don't know why; many online POV programs work with 5,6,7,8, or 10 LEDs. I'm not a skilled programmer. Normally, I'd use two Arduino Uno boards, but one was lost due to an incorrect connection. That's why the POV uses an Arduino Mega - it also works with an Arduino Uno. Since I originally planned to use an Arduino Uno, I kept the 13 LEDs. The threaded rod is 8mm in diameter and 150mm long; the two bearings are 608ZZ. The total height of the project is 220mm high. The outer arch has a 150mm diameter, while the inner rectangle measures 95mm high by 70mm wide by 15mm thick - with about 3mm clearance. This project is still under construction. My next steps will be to find a good program, calibrate it to reduce vibrations, and design better support for the POV so it won't fall while running.
