First post. Thanks in advance.
I currently have a small LED sign with 8 leds that cycle through the letters on the sign from left to right. I am using a 555 and a 4017 and it has worked great. However I'd like to add a few more details to the sign. Once it cycles through the 8 letters I would like it to flash all the letters on for 2 seconds, then off, then flash them on again for 2 seconds, then off, and then back on for 20 seconds. It will then repeat the entire cycle.
I'm looking for ideas on how to implement this. Thanks
