I'm wanting to build a circuit to control several outputs in a sequence.
So I'm wanting to use a 555 to drive a 4017, but the problem is that I want the 4017 to shift every 5-15 minutes (adjustable)
I can't seem to get the ratios of the resisters and cap right to only give me a high pulse of say 1 sec and low for the rest. How do can I make it only give a short high pulse, or doesn't it matter driving the 4017?
