Post on a (sometimes offline) blog at: http://robotics.reefat.com/2008/08/22/analog-to-digital-converter-demo-sensor-interfacing/ using the U401 and an ADC0804 for analog conversion. I’ll repost the pics and code here. Oddly, the video was removed because “Fox” considers it to be a copyright infringement. Um… ?? Someone needs to explain this to me… (Author doesn’t know why, either.)
