Hi all,
I bet this question has been asked many times. I’m newbie to the wonderful world of PIC’s and electronics.
I would like to build a voltmeter using 16F84A (have these at hand) and LCD to display the voltage.
The voltage I would like to measure is 0 – 16V. I assume I would need to use an ADC such ADC0831.
I know I will need to do some scaling, as the ADC will only be able to read 0 – 5V.
Need help in designing the circuit. I should be fine with the code side for the pic.
All the help given would be appreciated.
Thank you
