PIC 16F88 Digital Thermometer Light Meter and resistance ohm meter.

PIC 16F88 Digital Thermometer Light Meter and resistance ohm meter. My original idea for this project was simply to try and interface the WINTEK WD-C2401P lcd panel to the pic (see my previous post). I figured it would be fun to add a couple of ADC readings to display something useful on the lcd.  Theory of Operation: PORTB on the PIC is used as the data port for the LCD. The Enable, Register Select and Res ...
