Hello guys i'm new to electronics, i'm using a breadboard and creating a 7 segment, is it possible to only use chips and or chip without decoder to create single 7 segment display 0-9?
Also i'm confused, i have 2 switches connected directly to the common cathode of led display displaying number 1, if i press wither switch both light for example a and b disappears, i wonder why? Is my breadboard defective? If i push one switch it should switch off only one digital line but it switches off both, please help me understand what's happening. I would really appreciate the help. Big thanks in advance.
