I work in the medical field and we would like to have a small lcd display that would have 3 variables displayed that consist of 3 digit numbers 0 - 100. We would like to be able to change these numbers with either a computer or dial to simulate physilogic changes that relate to these numbers. What would be required and how complex would it be to program?

Thanks in advance for any info.

it can be done with a microcontroller wit LCD display.

for a computer data input you must know the interfcae (rs232/usb...)
for a standalone then the input dial decoding.
