Yes we set number of digits.
Iset resistor is 47k, but we tried a lot of different resistors.
What is long wires?
it`s about 5cm
We made it in two ways, we put everything on breadboard, and second way we made PCB. in both ways it was the same
maybe you can look ULN2803 and UDN2981 exact name.
)
And one more thing pull-up resistors, what are they doing? maybe we need to change those? we tried to change iset resistor, but nothing changed, we were able to see ghosting without iset resistor
