In previous lessons we mostly dealt with numbers adjusting counter step and clock interval. Now let’s talk about booleans. They have only two possible values:
Booleans are extremely useful and common. They may be used to indicate whether some condition is met, should a device be on or off, did some operation succeed, etc.
Let’s learn how boolean values can be combined.
tweak-booleannodes to change it to the opposite value.
Check out descriptions for
xor nodes. Add them onto the patch along with some additional tweaks to make a more complex processing.
If one would use binary sensors like buttons or mechanic switches as a source of boolean values and relays instead of watches, he can use XOD to program PLC devices resembling the ladder programming which is common in industrial applications.
