I'm very new to arduino, I'm doing a project at school and need to use a variable analog input to control a 2 digit 7 segment display; as the input increases, the numeric value increases.
i have an Arduino mini 04 chip. How do I get started?
The “fun” of 7 segment displays is that they come in many forms, and most of them can be driven in many ways.
There are all sorts of compromises to consider. Cheap displays are “hard” to drive. Fancy ones have electronics in them, not just the LEDs in a matrix.
If you have lots of digital lines to play with, then you can drive the display “simply”. If you want to drive it using just a few digital lines, then you start using tricks and cleverness.
