## Title: 01 Clocked Sandbox
!img:sandbox1.png
Sandbox mode with a `clock` signal that triggers when circuit is idle.

No objective.

`Inputs`

The `clock` input allows you to create synchronous circuits. It triggers `on` or `off` when the circuit gets idle (it won't update in a constant rate).

The `power_on_reset` input allows you to initialize memory when applicable. It stays on (`1`) for the 2 first clock cycles, then it becomes off (`0`) for the rest of the simulation.
