Thanks for the response! After some trial and error I think the issue is with the yellow LED specifically. My clock module will have a Flasing LED if I change the color to blue but it won't flash at all for

The positive end of the LED should be connected to Pin 3 of the timer and the negative ends need to be connected to ground right? If so I have it set properly, the Dev told me that the frame rate scaling of the LED ends up syncing with "off". Mine is based on Ben Eater's circuit .
