Hello every one,
I am new to the arduino world. I studies in electronic engineering and I made a personal project to learn and understand how to program things.
So like the title says: I want to drive a 7 segments display without any chip controller ( each pin of the display is connected to the digital pin of the arduino ). To drive the display, I want to use 4 switch (1 bits, 2 bits, 4 bits, 8 bits ).
I tried a lot of program without success, so I ask your help.
