Can an IC be programmed from a Microprocessor such as the Arduino Pro mini and can the stand alone IC output to an LCD display without the microprocessor?
Can the IC except input from an analog input and output to the display?
yes. but there are a few minor details to understand like what the heck the IC is, what you are programming it with and what the LCD is.
Thanks Philba, what IC can I use? I would use the Pro mini 328.16mhz/5v w/ a FTDI Basic Breakout - 5V and a LCD-00790 (Basic 16x2 Character LCD - Yellow on Blue 5V)
I would like the IC to read a battery voltage from a voltage divider via input pin. I would scale down 9v to less than a volt to input and possibly calculate for amperage and resistance.
You do understand that IC means integrated circuit? As such it’s a totally meaningless term in this context.
It sounds like you have all the parts selected so you just need to go look up how to use each one. Since you are using an arduino, you can find example/demo sketches for all that stuff on the arduino site. try each of them out and then borrow bits and pieces to put together for your project.
On measuring 9V, you’ll need a voltage divider (2 resistors) to get it into the range you want http://en.wikipedia.org/wiki/Voltage_divider
Yes, An IC like in Shrinkify your project so I wouldn’t need the Microprossessor in the finished project. Just the chip.

Of course I wouldn’t use this tiny chip but one that can handle the LCD.
Yes, I know about voltage dividers and have calculated my resistors.

The IC in the video is a microcontroller (MCU), just one with fewer pins than the MCU on an Arduino board. FWIW you can buy the same ATmega MCU used on an Arduino board, [with the Arduino bootloader already flashed into it, and then use it’s serial port to D/L code into the MCU, same as you would for an Arduino Pro. That’s just the naked IC. Or perhaps you might find one of the [RBBB kit options to your liking. You can make one as “bare” as you need to.](http://shop.moderndevice.com/products/rbbb-kit)](ATmega328 with Arduino Optiboot (Uno) - DEV-10524 - SparkFun Electronics)
