This is my first post on this forum. Usually I find answers to my questions by googling and searching through the forum but this time I'm too confused. Sorry if the answer is too obvious...
Well, I want to connect a 3-digit 7 segment display to my Uno. I tried it using the SevSeg library and it worked perfectly good (although I've read that putting resistors on the anode isn't the best practice). The only problem is that it requires a lot of pins and don't have many left with my current project.
I already have a few parts at home and would like to know if I can manage to make it work without having to buy new stuff.
I have a few 74HC595, PNPs and NPNs transistors, diodes, capacitors and resistors of many values.
So here's the final question : how should I wire my 3-digit 7 segment display in order to use the minimum pins on my Uno and without buying new chips ?
Codewise, I should add that I don't care using a library or not. I used SevSeg just to test the display.
I hope I made myself understood ! English isn't my mother tongue. Thanks in advance and I'm prepared anyway for the answer "that's actually not possible" ;D
