Hi guys, I am working on a PIC Voltage Meter. Apparently I should be using a PIC with a Analog input, and I have chosen a PIC16F88 for that.
I want to measure voltages up to 12 volts, and display it on a 16X2 HD44780 compatible screen. Apparently I need to have a resistor voltage divider for that, is there a formula to come up with the resistor values I need?
What do you think I will need for this project? I am thinking just a very simple PIC itself, resistor voltage divider, and LCD screen. The power supply I am using to monitor the voltage has a 5 volt output, so I am covered with the voltage supply.
Thanks guys, iflymyhelishigh
