POV with LPD8806 and Hall Sensor

Post by Msmith419 »

Hey folks,

I was wondering if anyone had attempted to do some POV with their LPD8806 strip. My basic idea is to strap the strip to a fan blade and use a hall sensor to measure rotations/s. Based on this, I would adjust the flash-rate of the LEDs to create the image. I'm still stumbling over the LPD8806 coding a bit and I'm sure someone has attempted this before. I'm also having trouble thinking through the code for getting rotations/s out of the hall sensor. Thanks for your help!
