I feel so stupid, i need a circuit diagram that seams so simple but i have search high and low but no luck
I need a simple 4 channel (or more) chaser circuit that switches on one channel at a time but each one stays on and needs to be able to power a small relay not just an LED so with "O" = on and "X"= off (if 4 channel)
Step 1) X X X X
Step 2) O X X X
Step 3) O O X X
Step 4) O O O X
Step 5) O O O O
Repeat
Ideally would like to use something like A 4107 chip and 555 with speed adjustment 12volt and trigger 12 volt relays
TIA
