delay function

This function is used to hold up system operation for a specified period of time. It is typically
used to soak a device at a specific voltage or current for a period of time.

Delays system operation.
delay(seconds)
seconds: Set delay in seconds (100000 seconds maximum).

This function will cause a delay for the specified number of seconds. It is
impossible to delay for zero seconds.

Delays smaller than 50µs (seconds) will be dominated by overhead such that the
actual delay might be as long as 50µs (typical). For delays longer than 50µs, the
delay may be as much as 10µs (typical) more than the requested delay.
To pause program execution for 50ms:
delay(0.050)
The digital I/O lines can be used for both input and output. If a line is being driven low,
then a "0" value will be read by a command for that line. You must write a "1" to all
digital I/O lines that are to be used as inputs.
Reads one digital I/O line.
data = digio.readbit(N)
N: Digital I/O line number to be read (1 to 14).
A returned value of "0" indicates that the line is low. A returned value of "1" indicates
that the line is high.
