The <clock> block generates a Boolean value that alternates between True and False; each state has a configurable duration.
•« t_on » : determines the duration of the high (True) states
•« t_off » : determines the duration of the low (False) states
•« clock » : this is the main output that alternates between True and False.
•« rt » : (Remaining Time): This is the time remaining for the current state. It is a stored variable, which explains the apple-green background color. It is initialized to 0.
The inputs are numeric; they must be of type: int or float
The “clock” output is of type bool. As for “rt,” it is of type float
