Each servo motor requires a PWM signal to control its position, and with 28 servos needed for the clock, the Arduino Mega’s capacity was quickly exceeded.

If you've got an Arduino of any variety, you might have noticed some of the pins on the board have a tilde mark or PWM printed next to them. What is PWM?

Behind the pegboard, a single, hardworking Arduino Uno controls three 16-channel PWM controllers that sweep the servos.
