RE: Steem Electronics #2: A Tutorial on how to construct LED chaser circuit screen - part 2
Good observation! I purposefully didn't want to talk about that part because I needed that question to be asked... 😀, now that the question has been asked, here is my response.
Normally, the CD4017 has 10 outputs, but the characters I wrote here are just 7, so what this simply means is that I have omitted 3 outputs without connecting them. I only made use of 7 outputs instead of using the entire 10 outputs.
So 3 empty slots are still remaining. (The circuit can still work even with such condition).
Thank you for that observation...
Maybe you could try building this circuit...? I could guide you.
manuelhooks will need 11 outputs, if each output was to care for an amphabet, one alphabet will not light up.
Putting two letters on one output will somehow help, but is there any other better solution?
Thank you for this educational post, i would really love to join the electro-fun.
Two letters on one bit can work.., however, another way would be to use 2 pieces of CD4017 IC to get that ine remaining letter.
Con un solo circuito 555 cuántos CD4017 se pueden colocar en cascada para sacar más letras? @ubongudofot
Check the response I gave to @ manuelhook the other user that asked such question.
