Here's the instructable I refrenced when I ordered the shift registers: http://www.instructables.com/id/The-74HC164-Shift-Register-and-your-Arduino/
I'm going to need to give this another swing soon.
Well, the tires are tiny, and really tight. So, I decided they aren't staying. They are also heavier than I hoped. The saddle is much nicer than the vader saddle.
The new seatpost and spacer look good. I think I like the yellow saddle.
Last Thursday I met up with Loclhst to show him how to use analog sensors with his arduino.
The process started with testing the photoresistor and thermistor on the bench with a voltmeter. We then set them up in a voltage divider, and fed 5v across them. That got us a voltage output we could send to the arduino.
Then we hooked up the voltage dividers to the arduino, and we got real values.
Then dan wanted to get his display working. After we discovered I had a wire crossed, the display worked fine.
