I'm new to electronics so I'm sorry if this sounds stupid.
I recently created an LED sign consisting of 97 LED's on a piece of wood that all light up at the same time when I supply it with 3v. I have watched a bunch of videos on electronics and I saw one that used the 74HC595 shift register to light up an LED sign one by one. (https://www.youtube.com/watch?v=Yexp-I8lzP4)
I came up with a circuit using a 555 timer and 13 shift registers (the photo has one too many) but I'm not sure if it will work and I don’t want to blow up all the chips when I plug it in.
My question is: Will this circuit work and is there a more efficient way to do this? Also, does the 555 need 5v as I heard it usually drops a couple of volts? How would I reset it a few seconds after the animation has finished?
Any answers are greatly appreciated.
