STAMP2 potentiometer P3 IN3 ???

wperko

Hi,

I want to use a potentiometer tied between VDD and Gnd with the middle tap going to a BASIC STAMP2 P3 ...

What is the BASIC input code to read the P3 value (0-1024???) or whatever it would be?

IN3, ?

Check the Basic Stamp Reference Manual for the RCTIME command. You'll need to add a resistor and capacitor to the potentiometer - the schematic is shown in the RCTIME command www.parallax.com/Portals/0/Downloads/docs/prod/stamps/web-BSM-v2.2.pdf
Note this will give you 8-bit resolution. If you need more, you'll need an A to D converter IC.
