i made a LED controller a while back using a 4017 and using 8 outputs... now i need to make it 20 outputs. i have 2x 4017, but not sure how to connect them so first one will go through 1-10, stop and start second, which will go 1-10, stop and start first and number 1 again.
i have connected output 11 of first to 15 of second, and 11 of second to 15 of first, but they both go through 1-10 at same time. which outputs should i be using?
