Build an 8-Bit Computer by Ben Eater (Part 1) - Clock Module

Build An 8-Bit Computer by Ben Eater - Clock Module (Kit 1 of 4)

The computer's clock is used to synchronize all operations. The clock you'll build in the kit is based on the popular 555 timer IC. The videos go into some detail on the operation of the 555 and how to use it in three different ways.

Our clock is speed-adjustable (from less than 1 Hz to a few hundred Hz). The clock can also be put into a manual mode where you push a button to advance each clock cycle. This will be a very useful feature for debugging the computer later on.
