My SQL Server blog. Adventures in building, hacking, tinkering. Arduino: figuring out shift registers. Arduino: Windows simulator of driving matrices of 8x8 LED arrays. Arduino: cascading shift registers to drive 7-segment displays with PC input. At 3:33 PM under Arduino. In the last post. A a - pin 14 dp (decimal point) - pin 9. B - pin 13 common cathode - pins 12 and 4. F b c - pin 8. G d - pin 7. E c e - pin 6. Dp f - pin 2. D g - pin 1. Ive also moved to a proper coding style, with g. Care must be ta...

Shane Colton: Self-Balancing Things
http://scolton.blogspot.com/p/self-balancing-things.html
As part of my interest in control systems, I've built or helped build a few self-balancing things. They all share the same basic angle sensing and control loop, but across very different hardware:. I built Seg.stick in two days, mostly as a joke. It's a minimalist self-balancing platform based on two DeWalt power drills:. So you can build your very own Seg.stick. Actually, I hope you don't. But the information and explanations there are applicable to any self-balancing platform. Which was Problem 1 of 5.
