I will be using the 14 input/output Arduino. My goal is to create a plane radio console for use with a flight simulator. I am very competent at writing code, but have little knowledge of electrical engineering. There are 3 readouts on the panel I am making, which will display the different frequencies. I need to be able to directly control each 7 segment display of the 12 total digits needed.
Which shift registers would I need in order to properly wire this? I want to use as little of the pins on Arduino as possible as i need to also wire up 3 rotary encoders and two On/Off switches.
Is this possible? If so, which Shift Registers do I need, and what Make/Model?
