I have completed building the circuit I came up with - LED array chaser (schematic included.) Really cool effects to use with signs or advertising.
It does work but I am concerned about the caps I have across each LED array (C2, C3 and C4 shown in red.) They provide the fading on/off effect for each blinking LED array.
The question I have is - Do I need to protect the 555 and 1047 from those discharging caps even though they are connected across the LEDs? (I'm thinking as the caps discharge through the LEDs, they also discharge back through those ICs.) Maybe I need to include some diodes.
Any suggestions are appreciated.
Thanks!
