This is a set of instruments that display the speed and altitude through LED, which can monitor the speed and altitude of the aircraft in real time. One instrument has 12 meters, which can display the ground speed, airspeed, altitude and ground altitude, and different units can be selected, as follows:
[GS(KPH)] [AltitudeAgl(ft) ] [ IAS(KPH ]
[GSMPH ] [AltitudeAgl(m)] [IAS(MPH)]
[GS(Knot] [ Altitude(ft) ] [IAS(Knot ]
[GS(m/s) ] [ Altitude(m) ] [IAS(m/s) ]

I think I understand, thanks for your help. I'll go try it out for my own!
@SnoWFLakE0s The input mechanism of a lamp is that it can be on as long as it is not 0. For example, a lamp needs to be on when x is 012, off when x is 345, and off again when x is 67. We can use the function of sign, such as sign (3-x) - 1, when x is less than 3, it is 0, and when x is greater than 3, it becomes - 2. In order to make the lamp on when x is equal to 012, we can first add a 2 to the front, that is To make 2 + (sign (3-x) - 1), when x is less than 3, the light will be on and off. In order to realize the situation we said at the beginning, we can write the function as follows: 2 + (sign (3-x) - 1) - (sign (6-x) - 1) + (sign (8-x) - 1, after simplification, it will become 1 + sign (3-x) - sign (6-x) + sign (8-x).

Oh my god
Hey mate, I have a way different method of doing this, but I couldn't quite understand the way that this one works. Could you explain?
How do I learn how to do stuff like this with LEDs?

This is a great design and the beginning of SP instrument digital display technology.
Great. Can I learn this design and install it on my plane
