Very nice! I decided to tie it into a few of the ball/microswitches on the child letters but like the coil diverter and left ramp gate aspect too.
I have one of these timer relays from amazon and the trigger is a ground when completed by the microswitch -> https://www.amazon.com/gp/product/B074V67ZT6/ref=ppx_yo_dt_b_search_asin_title
Do you have any pictures or details on your microcontroller setup for those two methods you mentioned above for the diverter/left ramp gate? Would be nice for me to add this as an option to trigger him
