Controller for a large "garland"

Question

Electronics

Advise a flexible, simple and reliable circuit (or just a controller on the basis of which to build) for controlling 10-30 12V consumers according to a given program. The task is similar to the illumination of the letters of a long signboard. Flexibility is needed to make changes to the program relatively quickly. The on-off ranges are close to tenths of a second.

Answer 1

Any microcontroller with the appropriate number of outputs + field devices for the load.
Or any controller with an inappropriate number of legs + shift register + field workers.

Answer 2

what is the consumer power?
controller - the simplest - arduino, plus a strapping from a relay and better than field-effect transistors in terms of load power.
