Motion Activated Led Dice using PIC16F688




Introduction

  I’ve always wanted to build an electronic led dice, but something different from what we see on the internet. Making it motion controlled… now that’s new!   Many new cell phones that have accelerometers built in also have dice games. These dice move when shaking the cell phone. My Led Dice project will also work with a shake motion but without the use of the expensive accelerometers.
