I'm sure you know how to start this! You can click the button on the bottom left to see the hammers. To set your chime, click the button on the bottom right to toggle between: Westminster, St Michael, Whittington, and Silent. You cannot change the chime melody when the clock is chiming. Click the button on left if you want to turn on/off ticking.
Inspired by Howard Miller. The next clock is another Howard Miller, but this time, the Westmont, available now: https://scratch.mit.edu/projects/996499027/
