Microcontroller based LM3914 Display Driver

[Mr.RC-Cam 123]

From time to time I read about how a simple bar graph display would be useful in a custom R/C project. For example, a battery level meter, RSSI display, fuel level, etc. Without fail, someone will recommend the old National Semi LM3914 display driver.

For those that want a little more flexibility, this application note might be just the ticket: Do-it-yourself analog-to-LM3914 display driver offers user programmability.
