Hi guys. Thanks for building such a kick @$$ site. I've read the sticky note for beginners, but I still have a couple of questions that I can't seem to find the answer to.
First off,
I'm working on a project where I'm going to have 3 analog 5v sensors as inputs. My PIC needs to process the info from these sensors and will be controlling 3 outputs (lights, motor, heater). I've read about analog versus digital and I'm a little confused as to how the signals need to be converted and how to program this conversion. Do I need to look for an analog PIC or can a digital PIC work just the same? OR...are all PIC's digital and need a special converter for analog?!?...AHHHHHHHH!!!!!!
Second Question,
I've been researching PIC's in general and I saw that you guys recommend the PIC 16F628. Before I came across this site, I had been thinking about an 8052 (I found some good tutorials on it). I know that the PIC16 has 16 (18 total) I/O pins and the 8052 has 32 (40 total). How will I know how many I/O pins my project will require? Could I run everything I need for my project with the PIC16's 2 ports or do I need 4 ports with the 8052? I guess I need to know how the ports correlate to the amount of devices the PIC itself can control.
Please help!
