Persistence of Vision Bike Light Project
This project will use a 3.3 volt Arduino Pro Mini clone that you will design the circuit board, housing, and software for. Persistence of vision is a psychological effect that allows you to see two dimensional images that were created by one dimensional flashing LEDs. Here are some similar projects:
- This is video shows some POV projects from Japan.
- [http://hackedgadgets.com/2007/08/20/arduino-pov/ An Arduino on a breadboard spinning.
- Another spinning POV display.
- Simple Code for a simple POV device using the Arduino
We will have an MMA8452 accelerometer that communicates via a serial I2C interface. The accelerometer will measure the angular acceleration, which will allow the velocity of the bike wheel to be calculated. This will make it possible to flash LEDs at the proper time intervals to spell words, draw pictures, etc, as you ride your bike down the road at night.
