Voltage Divider Front End as you can seen in the schematic the 82k resistor and 10 k trim pot is connected ias a voltage divider configuration .we all know very well that by default MSP430 microcontroller ADC reference voltage can be set to 2.5 volts internal reference . so what we have to do is make such voltage divider that can divide out maximum range 30 volts to 2.5 volts . so we need is Vin/12 ==> 30/12 =2.5v voltage divider . and to

PIC based digital voltmeter author: Rajendra Bhatt - rajbex[pic]yahoo.com Introduction This project describes how to make a digital voltmeter using a PIC microcontroller. A HD44780 based character LCD is used to display the measured voltage. The PIC microconotroller used in this project is PIC16F688 that has 12 I/O pins out of which 8 can serve as analog input channels for the in-built 10-bit ADC. The voltage to be measured is fed to one of the 8 analog channels. The reference voltage for
