When designing the input circuit of the key, we usually adopt independent IO port to connect the key or matrix connection.Matrix connections take up IO less than independent connections, but is there a better way? The simulation keyboard module is a good solution to this problem. It allows you to read the state of 5 keys with one simulated IO port, which really simplifies the circuit.When the button is pressed, the corresponding LED will light up next to the button.
