| Sep 6, 2018 at 18:09 | comment | added | mguima | Random starting output always seems to be a reset problem. First, I would try just groud reset (pin 15), and let output 8 (pin 9) and output 9 (pin 11) floating. See if this works (there will be a delay after output 7 turning off, before output 0 turns on). If this works, you should put a pull-down to reset pin; maybe the initial state of pin 8 is not enough to trigger reset. | |
