Hi
I suppose such questions have been posed upteen times but I guess a newbie like myself, searching thru the internet, get more confused than enlightened as I try to consolidate the answers for different sub-component. So I guess I might as well asked in one place. Thanks for your patience!
I am trying to build a system that involves a PIC microcontroller. Am trying to determine which one to choose. My requirements :
1) a LM75 temperature sensor - how many pins needed on PIC
2) 2 x 16 or 24 LCD display - 7 pins on PIC?
3) a photocell - how many pins needed on PIC
4) a speaker for simple beeps - how many pins
5) a 4x4 matrix keypad - how many pins
6) clock to tell time - "
7) USB port for upload/download to PC - "
8) RS232 port to send 5V signal to another relay device (??) - "
9) battery operated for normal usage
Based on the above, how many ports on a PIC would be needed? Any recommendations on the type of PIC (16F & 18F??) needed?
Many thanks!
