In the digital clock project, the AHDL block codes are connected using graphic design files.

In the frequency counter, a pulse shaper block is needed to ensure that the unknown signal, whose frequency is to be measured, will be compatible with the clock input for the counter block.

The direct drive mode of a stepper motor allows for less control by the operator.

The full-step sequence always has two coils of the stepper motor energized in any state of the sequence and typically causes 30° of shaft rotation per step.

In the digital clock project, a MOD-60 BCD counter is made from a MOD-10 counter cascaded to a MOD-6 BCD counter.
