landing gear / ABBA circuit
an ABBA controller / landing gear controller.
when powered, it activates A, the B.
when the unpowered, it then deactivates in reverse.
dont forget the delay between A and B with the number input, it is in seconds.
to me, this is the first ABBA controller, atleast that i could find.
it does hav minimal flickering at the end when deactivating, but you're gonna have to cope with that.
