Controlling individual relays refers to controlling relays by their designated numeric assignment rather than using the relay bank system we normally use. These commands were included as an alternative method of controlling relays to help suit the preferences of a particular user. Referring to relays by their numeric value may be easier for some users to comprehend, as relay 1 is the first relay on the board and relay 32 is the last relay on the board when working with a 32-channel relay controller. This section also includes relay selector command, which can be used to select the activation of one particular relay, ensuring all other relays remain off.
