I'm looking at building a circuit using two TCRT 5000 opti sensors to trigger the events. One for ON and a second for OFF. I had originally planned on using something like a 12F629 but may change that later to a larger PIC,if I decide to add more sensors.
Has anyone attempted this.? Had a search round the forum but haven't been able to find anything or similar projects.
All help or pointers gratefully received - thanks
I have not used the TCFT 5000 that you reference, but it appears to be a relatively standard implementation of a common sensor. Here then is some Basic Stamp code and usage information for a "similar project".
Parallax, by the way, has a TON of sensors (and information) to interface with their Basic Stamp - a device that is programmed with a similar BASIC to PicBasic. As a "noob" I often look there first; their documentation makes it easy to evaluate the complexity of the interface, measurement range... and guides me to hardware I can easily use. I believe that a fair number of hobbyist Pic users began there.
All the best in the new year--
Just curious, have you considered 18F PICs?
Price difference is low and features are endless:
