I paused on multiplexing those Dot matrix's for lack of programing experience.
I have switched to something simpler. Multiplexing 7 segment displays.
I have it coded and working. Now I want to make a pcb and the resistors on the bases are taking up too much room.
Do you really need resistors on the base of transistors?
Currently on the breadboard I have resistors on all bases.
Also that 7805 gets really hot. How can I fix that?
Also what else can I do to make the pcb smaller
