Scaling ADC Result to a Set Range

[RossWaddell]

that's cool...... 1 count in 1023 is small..small error..... that error with 0 volts could be where pic ground is in relation to pot low end...... ground pot low end close to pic ground.....
what about the fluxuating readings ?

Now that I'm not using PBP's ADCIN the readings are rock solid.
