URGENT! SCIENCE EXHIBITION DUE TOMORROW. HOW DO I RUN 16 SERVOS FROM ONE SINGLE BLUE PILL?

So I've read a lot of articles and asked bunch of questions to different ais.

It's said the 4 timers can be utilised to run 16 servos through pwm signal. Or running 12 servos from 3 timers, and running servo.h (12 servos) in the 4th timer.

I Ij just honestly want 16 servos to run anyhow.

Has anybody tried it? Please dont mention about pca servo driver. I dont have it, the exibition is due tomorrow. Please respond. Please dont hate i am posting this in a Arduino community i js need the help y'all..
